Histrion, how do others dress in the clubs you visit? You could get an idea of what to wear by looking at them. If I'm going to a rave, I'll break out the biker goggles, trendy tee, some bracelets, and baggy cargo/bondage pants (you can find these all on ebay by searching for 'rave goggles' 'rave pants' etc... mix and match!) along with some comfortable clogs or shoes. If it's a trendy club, you can go for a track suit (the shinier, off-colored ones are a lot more fun) and running shoes. Top it off with a head visor and maybe an LED blinking necklace, and you'll be ready to mingle with the fine ladies in their Juicy Couture. Again, you can check out ebay to get an idea (Adidas track suits and visors are dead-on trendy so you'll find them in droves right now if you search - so are those LED necklaces). Everyone else has great ideas about mixing and matching with jeans, tees, buttondowns, etc. Hope you assemble some outstanding ensembles!
