Oh, and another thing - definitely don't try to get strippers (I think that's what Ralph meant when he said "cabaret dancers") as models. They may be comfortable being naked in front of strangers and/or a camera, but they're about the least reliable models you'll ever find - they'll really irritate you if you go out and buy a whole bunch of film expecting them to show, and then they don't, and you hear from them a week later with some lame excuse as to why they didn't show or didn't call.
