Im 5'7, black, female Halloween ideas?

Im a 5'7 black girl 23. Im about the color of Gabrielle Union (actress) and have black hair about about an inch p my shoulders (pretty long). I want to be a celebrity for Halloween but I can't think of anyone who stands out (i.e. Paris Hilton, or like my friend was Anna Nicole last year). I wanted to be a famous celebrity but who could I be?
