Hey, Zach. I share your "hate" (although, it's not really a very strong emotion for me) for mainstream fashion. I think if your lifestyle allows you to avoid that, then you certainly can. (I work in the game industry, so I'm free to wear almost anything.) Do look into alternative fashion. Look at things you like. Check out interesting websites like etsy for items that are pretty awesome and might give you interesting ideas.
Look at different subcultures and steal from them.
