Here's a topic that can take over your life: cosplay. If you are unfamiliar with cosplay (short for costume play), it's a subculture of anime and sci-fi enthusiasts that combines role-playing and fashion into a type of performance art. Cosplayers are often are very dedicated, spending all their free time and money on impressive and elaborate outfits.
I've been speculating that ancient Greek, Roman and Egyptian wear will be the next steampunk. The fashion pendulum usually swings between excessive detail (i.e Steampunk) and simpler, classic lines. But the ancient Mediterraneans had more than nicely draped bodies going for them in the fashion department.
