Ok I need some help with a Halloween costume. Do you have any ideas?

Im going to a halloween party to a bar dance hall. its 21 and over. some of my girlfriends are going as a cheerleader, a y maid ,and a which. I really don't have any ideas or anything this year im stuck. This is what i have I have a black leather high midriff halter top or a black spandex high midriff halter top that has a wide open keyhole in the middle. and for the bottoms i have a black mini skirt,black leather tight pants.or black tight short shorts. I was thinking something like a bicker chic,or a y vampire or something gothic. I have the body so need to worry about that. Just need some ideas on what i got.
