People say, “Oh well, you know, I don’t care about fashion.” They go to the Gap, they go to Old Navy, and they all dress alike, they wear these uniforms. The thing that I really harp on is that, that in and of itself is a choice, it’s a personal choice, because there are many people who don’t do that. In buying those uniforms, you’re saying something about yourself, and about how you feel about clothing and culture. There is no such thing as an unaffected fashion choice. Anti-fashion is fashion, because it’s a reaction to the current visual culture, a negation of it.

What you wear is as much a signal of who you are as anything (more so than many things). There is nothing inherently wrong with sending any particular message, but pretending that you aren’t doing so robs of you intentionality. Instead of being in control of the message, you send a haphazard signal. It’s a waste.
