What to Wear?

I was thinking of going to a costume party for Purim on Saturday night. Being so last minute, I have't really thought of a costume. Two things that are important at such a party, in order to be approached by a member of the opposite sex (if you wish for such a thing to occur):

1.You want to be recognizable
2.You want to look good.

That means no masks or excessive clown makeup, no stupid costumes like dressing yourself up in a huge box of Fiber One and calling yourself "The Regulator," and no woman, unless she's married, should be dressing up as a pro-football player. That said, I think most females know to take this oppourtunity to dress as skankily as possible and then claim to be dressed up as a supermodel rather than a slut. As for me, I'm leaning towards either flamenco dancer or flower child (so original, I know).
