depends on what the place is like. Ask one of your girlfriends what it's like and look up the place online - you'll probably get some pics online - then you can judge how you should dress.
A smokin' hot shirt and dark jeans with heels or boots. I wouldn't wear a skirt but it depends on where you are going and the length of the skirt. Also, I would stay away from graphic tees or shirts with pictures simply because it gives all those nasty drunks an opening for conversation with you. D:
When I go out I do nice jeans, sparkly belt, a nice blouse/classy tshirt or tanktop, pretty unique jewelry, and bright coloured highheels!!
But Im strange!
