I don't really listen to any EDM, but my friend wanted to go so I said why the hell not. Anyway, what is the typical dress for this type of thing, should I be on drugs? Is this even a spot I should try to approach women? If so, how? Just go up to them and grind? Any info on what I should expect, how to approach, what is the dress, is greatly appreciated.

edit: Great info guys. Thanks.
