Put it this way, guys don't go to clubs to look for a relationship... the more slutty you dress showing more skin, the more guys you will get coming onto you. Douchebags and all, pretty much you will be singled out to dance with if this is what you really want. Just be warned, although the more slutty you dress, the more guys you will attract. Many guys will feel they can take advantage of your "openess"
Hot, hot, HOT body. It's not about the clothes, ladies--it's about the body underneath. You can be dressed relatively conservatively, but if you're body is smoking, you'll get noticed. And you can wear the sluttiest clothes imaginable, but if you're built like a dump truck, it won't make much difference for most of us.
tight clothes, slutty behavior, smiles. A lot of make-up without being pretty will get you far because A) we've been drinking and B) it's dark.
