Something that is very common to science fiction movies involving future civilizations is a common wardrobe shared by most of the characters. Future cities, alien civilizations, and advanced people in the minds of our science fiction writers seem to give up on a world of distinct fashion in favor of some type of sleek outerwear that has minimal variation from one person to another. Everyone is in the same sleek silver jump suit. Everyone just wears the same indistinguishable plain clothing. The future is not fashionable, its practical and efficient.
I find future clothing interesting because it seems to be saying something different than what we say with our clothing choices today. In a movie, the unimportant background characters all wear the same clothes because they are not supposed to be the standout focus of the film (also a set designer and costume manager would go crazy coming up with 500 different costumes for different people). A lot of our future societies are also either utopian or dystopian, and a sense of individuality is either erased by a tyrant or given up by the society in favor of the collective. Clothes become a way to say, “I’m one of us,” rather than a way to say, “I’m me.”
In The Elephant in the Brain Kevin Simler and Robin Hanson talk about the hidden messages that our clothes send to other people. They write, “Today there’s a stigma to wearing uniforms, in part because it suppresses our individuality. But the very concept of individuality is just signaling by another name. The main reason we like wearing unique clothes is to differentiate and distinguish ourselves from our peers. In this way, […] the most basic message sent by our clothing choices [is] – I’m my own person in charge of my own outfit.”
We choose clothes that say something about us. They signal the groups we belong to, how much we adhere to social norms, and what kind of person we think of ourselves as. We are not just trying to look good, we are trying to give people extra information about ourselves so that they know a little bit about who we are without having to interact with us directly. In movies they tell us who are background characters we can forget about, and in science fiction they tell us that society has congealed together in an efficient and unified manner. Today, however, they tell the world how special and unique we want to be.
