"I'm not sure why we do it, but it's very hard to stop when everyone's doing the same thing. A lot of human stuff is like that, really. I can't, say, wear anything that doesn't say something about my gender, even if it's 'look how hard I'm trying not to have a gender' - and if I do that I'm sacrificing important opportunities to use my clothes to say 'I am rich and important and paying attention to all the things that matter to people around me'. Which is important to say for other reasons, but is only ever said in gender-based ways."
