Costumes reflect both a character’s culture and personality. Everything in their environment shapes the way they dress. Unless you have a professional costumer to defer to, costuming is left to the worldbuilder. When done right, a costume tells a story all on its own.
What we wear has two main purposes: function and expression. The functional aspects of clothing are dictated by the wearer’s occupation and location. The expressive aspects of clothing are the elements of dress that exist purely for visual communication. This includes: the denotation of status, class, allegiance, gender, sexual orientation, and personal opinion.
Function
The superfluous gears and cogs of steampunk, the absent holsters of the Star Trek uniform, and the uterus empowering tummy exposure of superheroines all illustrate that function is the bane of costumers’ existence. It’s true, practicality can get in the way of a “look.” However, the function behind clothing can be the worldbuilder’s best friend, especially when they are trying to create fashion for fantasy or science fiction genres. “What do people do while wearing this clothing?” and “Where do they do it?” are often the easiest questions to answer, and answering them will guide your research into appropriate solutions.
Environment

Clothing has been crucial to our expansion across the world, allowing us to survive outside of our natural environment. With the right clothing, we can withstand the extremes our planet has to offer. Those extremes might include:
- Temperature: The temperature dictates how much skin can be exposed, how thick or thin the clothes need to be, and what materials are needed to make them.
- Radiation: From flesh-dissolving exposure to mundane sunlight, radiation dictates whether it’s safe to show skin and if your characters will require hats, parasols, sunglasses, or full-coverage radiation suits.
- Water: Whether as precipitation, in lakes or rivers, or as crashing waves, water dictates whether or not – and to what extent – the characters need to be waterproofed. Things like rubber boots, umbrellas, and wide brimmed hats could meet those needs.
- Wind: The strength of the wind dictates how securely clothing must be fastened, and how quickly those umbrellas and wide brimmed hats will blow away.
- Surfaces: The nature of the ground – pavement, cobblestones, sand, rocks, ice, mud, or covered in grass – will shape the shoes characters wear.
Occupation
The occupation and/or recreational activities of characters will also affect what functions their clothing serves, such as:
- Protection: Characters often require specialized protection, since heroes tend to have dangerous occupations: hard hats for construction workers, armor for knights, goggles for airship pilots. Each occupation comes with necessary gear. What does your character need to be protected from? Fire, blinding light, falling objects, water, toxins, and combat are all occupational hazards that must be handled in order for your character to avoid injury.
- Mobility: The range of motion or lack thereof will dictate how well your character can do their job. Ninjas, Roman soldiers, and speed-based superheroes all tend to choose agility over shielding.
- Tools: Nearly every job comes with its own tools. How those tools are carried is dictated by need and practicality. Batman, for example, needs a utility belt, not a tool box; he has to access his tools on the go. Theater techs are in a similar position. They need a tool belt because they work at the top of tall ladders. How quickly does your character need to access their tools and/or weapons, and which of them will they choose to carry with them?
Augmentation

Consider whether your characters require augmentation. If so, what kind is available? Augmentation has two different purposes:
- Enabling the Disabled: The most common occurrence of enhancement technology is assisting the disabled. Whether your characters use wheelchairs and glasses, or hoverchairs and robotic eyes, they’re not aiming to transcend humanity. These characters use technology to access parts of the human experience that their anatomy has denied them, such as mobility, communication, and the five senses.
- Transcendence of Humanity:* Our clothing and accessories allow us to exceed our physical limitations. Stilts increase height, jet packs/boots give flight, and solar-paneled fabric gathers energy. Bluetooth devices and Google Glass extend our ability to communicate and access information through accessories. While there are endless ways to augment a body to exceed natural limitations, a culture will only create what they need. Clothes are tools and every tool requires a purpose.
Expression

Humans are visual and social creatures. No matter the culture, clothing is usually one of the ways we communicate. Fashion takes on a language of its own that, for the untrained eye, can become rapidly cryptic. While the code behind visual cues varies, what is being communicated through them remains constant: status, gender, sexuality, and allegiances.
Status

Civilization means hierarchy, and clothing is used to denote status. Most often, what clothes are available to whom is dictated by material production and economy. For those with low status, they are allotted the materials that exist in abundance and are easy to refine, because that is what they can afford. Those of high status can afford to show off rare and labor-intensive materials. Sometimes a culture will go one step further, banning the newly rich from finery enjoyed by the established, or the nobility.
What is rare depends on the world and time period. Metals, dyes, silks, or industrial materials are likely to be scarce. In our world, the Industrial Revolution profoundly changed fashion. Before the creation of an abundance of varied cheap clothing, the poor typically had two primary outfits: one for work, and one for celebrations. With access to an enlarged wardrobe, the lower classes began to use their dress to express mood and identity. Status is presented differently from culture to culture. Typically, the display of abundance is a theme, but core values change the way it is expressed.
A culture filled with gentry is characterized by leisure. Typically the elite have delegated most of the work to the lower classes, creating for themselves an excess of time. They may still use force in specific circumstances, such as a duel of honor, but for them, charm can be an equally powerful tactic. They must appeal to those of higher status than themselves. Their fashion may be pulled from the natural world, inspired by species that have evolved to draw attention to themselves: flowers, fruits, ornamental birds, and so on.
Non-working classes can show off their abundance without worrying about being encumbered. Their clothes can be voluminous and heavy, and jewelry and fabric can be exceedingly fragile, because there is no expectation of practical movement. Elaborate and delicate decoration is inherently expensive to produce, so it becomes another means to display wealth.
In contrast, warrior cultures may be defined by constant battle or constant movement. While there might be displays of abundance through the use of costly materials, the focus would be on fight readiness. They may value clothing that doubles as durable armor. Because dominance in such a culture is won through strength, the ability to be charming is not valued. A warrior’s status may be illustrated using clothes that appear intimidating, perhaps drawing visuals from predatory animals or spoils of war: scalps, bones, teeth, or pelts.
The expression of wealth in high tech societies may be shaped by advances in medicine. Services such as plastic surgery and cosmetics would enable the rich to keep their bodies in a state of near perfection. In a culture such as this, high status clothes could be very revealing and made with little material. In such a world, where physical materials have become abundant, wealth may instead be displayed in the form of designer and brand names.
Gender and Sexuality
Sexual Dimorphism

If your characters are part of a species that uses sexual reproduction between two or more sexes, there is likely to be sexual dimorphism; physical differences between biological sexes. (Self replicating and hermaphroditic creatures, if they are all equally capable of reproduction, obviously won’t.) Sexual dimorphism occurs naturally, but for us humans, the concepts of male and female have transcended our anatomy and have become symbolic: gender. Visual cues to denote sex have become tools to express gender identity. Cisgendered, transgendered and genderqueer individuals may all use gendered clothing to exaggerate or contradict their biological sex. On Earth, we have yet to invent clothing symbolism that expresses gender identities outside of the binary. We are limited to clothing that either emphasizes femininity, emphasizes masculinity, or doesn’t make a strong statement about gender. Your culture might be different. It could have clothing that advertises an additional gender, or signals an agendered status.
Attraction
Advertising one’s sex can expedite the process of finding a sexual partner or partners. Generally, the differences created by sexual dimorphism tend to be considered attractive: women’s increased hip to waist ratio, men’s widened shoulders and jaw. As a result, clothes have often been designed to advertise our sex. Corsets, shoulder pads, and makeup have all been used to reproduce and exaggerate existing sexual dimorphism.
In addition to exaggeration, there may also be purely symbolic gendered fashion symbols. As they are symbolic, they will vary from culture to culture and have no hard and fast rules about what they are or when they change. For example, in the West, male children and female children are associated with blue and pink, respectively. This originates from arbitrary decisions made by clothing manufacturers. Baby clothes had previously been gender neutral. Rumors that the wrong-colored jumper could pervert a child prevented the reuse and sharing of baby clothes between boys and girls. This pushed parents to buy more clothes than they needed.
Sexuality
Just as advertising one’s sex can expedite the process of finding a sexual partner, so does advertising sexual preferences. Those interested in a same-sex partner may break away from their gender-assigned dress in order to indicate that they are not interested in the opposite sex. Sexual preference is not limited to sexual orientation. The abstinence community has their promise rings. Furries wear their tails and ears. Practitioners of BDSM wear subtle collars or cuffs. Depending on the tolerance of the culture, sexual preference cues range in their subtlety. In cultures where heteronormativity or other strict sexual norms are enforced, clothing used as visual cues for sexual orientation or preference will generally be extremely subtle or nonexistent.
Patriarchy, Matriarchy and Equality

Another purpose of gendered attire comes back to the designation of class. Whether it is a matriarchy or patriarchy, like in many caste systems, the differentiation of clothes will denote the hierarchy. The Ferengi from Star Trek are a perfect example of this; their costumes are completely dedicated to the presentation of status. As Ferengi females had no status, they were naked by law. In this situation, the gendered dress predesigned to augment sexual dimorphism gets tied to the concept of dominant and submissive castes. Ishka wears clothes to symbolize her empowerment, and when Quark is forced to cross dress he is mortified to present himself as lesser.
In extreme cases, when one sex is considered property of the other, the dominant sex may use the other as a means to display status. Would-be spouses, children and slaves will be decorated to be more appealing, so they are easier to sell, trade, or contract in marriage. The decorations may extend to physical alterations, such as long nails or foot binding. Nonfunctional hands and feet illustrate a person does not have to perform physical labor, thus advertising their owner’s prosperity. This practice can be seen in the Clone Wars episode Monster. The Nightsisters, a matriarchy, sell one of their men to be a warrior for Count Dooku. In preparation for the sale, the male, Opress, is altered and decorated. Magic elongates his horns and increases his muscle mass. His clothes exaggerate the broadness of his shoulders, and he is armored. These changes are designed to make him more appealing to the buyer.

What is considered gender neutral attire can be shaped by a culture’s gender hierarchy. Matriarchy or patriarchy, the dominant gender tends to be considered the “default” while the lesser gender is considered the “other.” This results in patriarchies viewing masculine dress as “neutral” and feminine dress as sexualized.
Gendered dress does not inherently indicate that one sex is dominant over the other. However, a culture that is built upon gender equality has less reason to enforce a gendered dress code. While the influences created by sexual dimorphism may remain in fashion, they would not carry the same concepts of dominance and submission that they do in a hierarchy divided by gender.
Are the genders in your world treated as equals? How is gender expressed? What gender does your character identify as? How much do they define themselves by their gender?
Coverage
Across cultures, different body parts are fetishized and vilified. When a culture dictates that a part of the body has to be covered up, it endows “it” with symbolic power. This power can be considered positive or negative. Genitalia has both positive and negative symbolic power in many cultures. An extreme example from Nigeria is “the curse of the nakedness.” The curse is performed by women exposing their genitals to those they desire to curse. With this exposure they say, “We hereby take back the life we gave you.”
Geisha’s wrists and Victorian ankles owe their desirability and taboo to the restrictive dress codes of their respective time periods. Bare breasts, while in our culture are considered sexual and immodest to display, are considered normal by the Himba in northern Namibia. Instead, they view bare thighs as indecent. By covering up skin or specific body parts, a society artificially creates value for those areas covered by making them rarely seen. This creates a common phenomena in patriarchal societies: there is a desire to see naked women, but the act of a woman revealing herself “degrades” or “cheapens” her.
In many cultures, religion plays a heavy role in how the naked body is perceived. A belief that biological urges stand in the way of our spiritual ascension may motivate the enforced covering of the body. In contrast, a belief that the body is a perfect creation may encourage nudity. Whatever the stated reason, the dress code constructed by religious beliefs exists partially to illustrate allegiance to that religion.
Modesty and Consent: A Public Service Announcement
Allegiance
Uniforms
The repetition of a uniform builds familiarity on a psychological level. It masks individuality in order to encourage those who wear them to view each other as the same. In essence, it works on the “us versus them” mentality, creating an “us” that the wearer belongs to. Uniforms are also utilized to keep track of those wearing them. Organizations that use them want their students, soldiers, prisoners, and employees to be easily identifiable.
Especially in American fiction, which often uses uniforms to symbolize fascism, it is easy to see uniforms as scary. Uniforms in fiction are often used to communicate the loss of individuality, loss of power, or institutionalized brainwashing. While uniforms can be used to elicit fear, they are also utilized to communicate positive forms of solidarity. In Star Trek, for example, the Starfleet uniform was used to show humans united in a hopeful utopian future.
Uniformity is not bound by the limits of militia, fast food chains, or education centers. Most people dress under the guidelines of what appears “normal” in response to peer pressure. Depending on the culture, normalcy traverses a range from accepted diversity to rigid uniformity. As normal is relative, the worldbuilder dictates what is the enforced norm in their culture.
Subcultures
For every culture there is a counter culture. However, fashion is not just defined by conformity and nonconformity. Fashion is a form of expression, so it is logical that within fashion there is dialogue. We use our clothes to express our personal opinions – from acceptance to defiance. Just as we advertise our gender and orientation to attract mates, we advertise our interests in order to attract like minds.
Subcultures generally rely on two things: free time and a large community. Subcultures each have their own fashions that are used to express allegiance. If resources are so scarce that survival takes all of the community’s energy, there is little left over for self expression. Art, math, and science all took off once there was a food surplus, and it is no different for fashion. In general, prosperity leads to time and resources that can be dedicated to self expression. Small communities, like tiny towns and villages, can maintain uniformity through peer pressure. Larger communities, like cities, are too large to maintain a cohesive community. They naturally subdivide, leading to diversity. The internet, by creating many virtual communities, has massively furthered diversity in fashion, as it has in all forms of expression.

Costuming is not at its best when it is viewed as a process where the creative “makes stuff up.” There are many costumers who endeavor to design costumes that just “look cool.” Costuming shines when the characters appear to dress themselves. If what they wear reflects their culture and how they relate to it, then the costume has achieved its purpose: to enrich the story.
P.S. Our bills are paid by our wonderful patrons. Could you chip in?
Gender and sex are two different things. Gender is psychology and culture. Sex is biology. There’s nothing in biology that says we should throw temper tantrums if someone’s clothing and self-identified gender do not match the cultural conventions for what their sex should wear.
A comment has now been deleted twice from this post because it makes the erroneous and harmful statement that gender does not exist outside the traditional binary.
While we at Mythcreants love us a good debate, we will not sit by and force non-binary people to defend the fact that they exist.
I managed to see and reply to what was probably the second time. I really don’t understand the insistence that people conform to narrow cultural visions of what a “man” or “woman” is. The insistence of some vague biological imperative to conform baffles me. It comes across as a denial that culture and individuality exist at all, instead asserting that we’re slaves to genetic predeterminism and have a moral imperative to stop pretending to be anything other than our designated caste, for the good of the hive.
I’m a hetero white cis-male, and I’m not arrogant enough to assert all other people with the same equipment downstairs have a duty to be reflections of me. I’m not a fan of pink, but I’m not going to scream bloody murder if I see someone with XY chromosomes wearing pink.
Yeah, guy came back a third time and it just got worse so we eventually had to block him, though I appreciate you challenging his statements.
If I’d thought he was interested in learning we could have talked about how gender and sex aren’t the same thing, and how even sex isn’t a simple binary, but he seemed more interested in judging others.
I’m glad you’re keeping a close eye on the comments, because I really appreciate the open and positive discussions I find here.
I’ve never seen gender as something solid, it’s always been something fluid for me. And I found this article very interesting and instructive.
I’m a nonbinary person living in a conservative culture, where most people haven’t heard of anything outside the gender binary. I’d just like to thank everyone here for being supportive because I don’t get much of that in everyday life.
Sorry you don’t get to experience much support of your identity where you live, I’m glad online communities can help.
After watching a lot of videos by dress historians, I would also like to add ‘look up several sources for a fashion topic and rather listen to historians than historical sources that are common.’
Corsets were by far not as bad as a lot of modern stories made them look. It also pays to remember they were worn by all women, not just by the rich ladies who lifted nothing heavier than a tea cup all day. That maid in the last picture up there was wearing a corset while tighening the lady’s corset. Also, why did she do it after the lady had dressed? Before the 1980s, corsets were normally worn beneath the clothing. A lot of the bad rep of corset comes from Victorian men (who despised the huge corset industry they had no access to) and modern feminists who use the corset as a short for ‘oppressed women’ – which is not how it was.
The whole ‘dress like a realm man’ (in dark and mute colours) is also completely off-topic, as there was a much longer time in history where men with money dressed colourful than where men with money dressed in muted colours.
Can somebody explain to me how more than two genders exist? I genuinely don’t know and I live in a conservative country that doesn’t recognize more than the two genders + intersex. I’m not trying to offend anyone I just don’t understand this concept. I find it strange, because back then gender and sex were interchangeable terms.
Gender is society’s idea of what is masculine, feminine, or neutral. It can and does change. My favourite example, but there are a lot of others, is how in Ancient Greece a ‘real man’ was supposed to cry in certain situations while in today’s western culture ‘real men don’t cry.’ We’ve not changed physically in the meantime (not that much at any rate), but the understanding of what makes ‘a real man’ has.
Sex is biological and can be defined through genetics (XX or XY) or physical appearance (which kind of genitals they have). While scientists for a long time thought that it was binary (male or female), it isn’t. Even looking at genetics isn’t binary and there are indeed intersex people who either have both genitals or one that isn’t clearly recognizeable.
As ‘gender’ is a social construct, essentially a list of ‘dos and don’ts’ for those considered masculine or feminine, gender can easily be expanded or completely cast aside. There’s no biology behind it, nothing which is unchageable. Therefore, gender also doesn’t have to be a binary of masculine and feminine. There can be many different approaches at gender.
Editor’s note, I have removed a comment because it went beyond asking questions and into bigotted territory. We’re happy to answer questions, but we will not host a debate on trans and intersex people’s existence or their basic rights.
I know this comment was removed, but I have a RANT that I want Karam to see.
No, transgenderism is not a “cool fad.” Fads are things that are socially accepted, encouraged, generate positive responses, etc etc. Coming out as trans, in the vast majority of cases, is NOT that. Transition means excessive skepticism, scrutiny, and even outright hostility from those around you, and that’s in the best of cases. You are deemed mentally unwell, “genetically defective,” or otherwise “lesser” and somehow sick and stigmatized, implying that transgenderism itself, by which I mean being transgender (the classification of gender dysphoria itself as a medical condition is complicated), is a medical problem that is deviant and abnormal and therefore would be better if it were “fixed” and did not exist. If you have to explain away transgenderism as something to do with health deficiency, then yes, you do have problems with trans people. (Always be wary of “I have nothing against X group, but…” in just about any context.)
The “kids” you mention who come out as trans? The ones you say are “joining” (ie, choosing to follow) that “cool fad” and “making” new genders? They experience bullying, assault, disownment from their families, isolation from their communities, and outright abuse (https://tinyurl.com/3nxx8k4e). Abuse that is currently being legalized in the US on the premise that trans people don’t know what’s best for them and that it’s in the parents’ best interests to abuse their children out of being trans. Suicide rates are high among these (https://pubmed.ncbi.nlm.nih.gov/32345113/). Trans people are subject to higher rates of sexual violence as well (https://ovc.ojp.gov/sites/g/files/xyckuh226/files/pubs/forge/sexual_numbers.html) and this is once again showing high rates in the transgender youth you claim would choose this. Because it’s “cool.” Some cannot come out for fear of these threats to their safety and lives. I guarantee you these closeted trans people are around you, very justifiably fearing the people who reduce their identity to mental disability and who will beat them up if they use the “wrong” restroom (https://www.nbcnews.com/feature/nbc-out/trans-teens-face-higher-sexual-assault-risk-when-schools-restrict-n1002601), when these trans folks pose no threat to the cis people who share their bathroom (https://www.nbcnews.com/feature/nbc-out/no-link-between-trans-inclusive-policies-bathroom-safety-study-finds-n911106). These may seem like innocent beliefs for you. You yourself probably would not go to these extremes of violence. But those who would hold the same beliefs, and clearly, they are harmful and dangerous.
No. Transgender kids come out IN SPITE of every pressure, every threat of abuse and neglect and violence. It’s an act of bravery. Not an act of following some passing fad. Not because they are mentally unsound. They come out because they are trans. I don’t know how to make this clearer.
And this is all without mentioning the fact that third genders and trans people have existed throughout all of history. I’ll leave that research up to you, since it seems you didn’t look into many of these other easily-available statistics about widespread violence against trans people.
Also, none of the broad and oversimplified arguments about sexual dimorphism apply to the society we’ve built. Even if those were true back in the days where we had to hunt our own food (and I am skeptical of this), we are not in a “survival situation” anymore. In fact, you yourself say that males are “expected” to be masculine and females are “expected” to be feminine: what is “expected” of us is not what we are.
I’m glad you admit you don’t know everything. Please go on educating yourself. Rant over.
To add to the bathroom thing, there’s a corollary “concern” where people worry about creepsters posing as trans people to peep on cis people in bathrooms. To that I say, that’s a creepster problem, not a “trans people get to use the bathroom” problem. Especially since cis people are just as capable of creeping and peeping on each other in the same bathroom. (Honestly, it’s a “public restrooms suck in general” problem…)
Coming back to this yet again after doing some research on gender dysphoria and its classification, which I didn’t really touch on and actually find a very interesting subject. The long and short of it is, whether or not it should be considered a mental condition is contentious, as is using it to define transgenderism. The fact remains that not all trans people experience extreme dysphoria; many, a significant other of mine included, just feel a strong orientation towards a gender that’s not the one assigned at their birth and an apathy towards that assigned-at-birth gender rather than an active pain. An interesting article on these facts: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6225591/
There are a few schools of thought about this even among trans folks, from what I’ve read. One objects to the classification of trans people resting on an experience of significant mental anguish. Another sees it as validating to have a medical foundation, especially since right now that’s the bar for what insurance will cover (the surgeries and treatments would be considered “cosmetic” otherwise).

TL;DR: dysphoria is complicated and controversial as it relates to defining trans-ness; not all trans people experience it, and certainly not all to the same extent. It’s not classified as a “mental illness” as far as I can tell.
