Halloween Hairstyle needed!?!?

My boyfriend and I are dressing up as mobsters for Halloween. My costume is a skirt and top with white pin stripes. The top is midriff and has a white collar/lapel style. I need a hair style to wear with it and looking for ideas. My hair is short and brown. It's shorter in the back, longer in the front. (Ya know, the popular do that's real short). Any ideas!? Help help.
