Costume idea for a woman with a black bob haircut! 10 points please help!!?

Hi! I would really love some costume ideas. I have a black bob haircut so i'm trying to fit it around there. I really want to be a character for something, I wanted to be poison ivy but i've given up on that because of my hair, so the only other choices I can think of is Betty from the flinstones and Snow White... any other ideas would be great!!!!!!!!! 10 points to the person who gives the best costume idea. It is for halloween but I don't really want a spooky costume. Thanks! x
