Halloween costumes?

So now I'm googling around for Halloween costumes, and I'm not sure what I want to dress up as! I have an idea, but I don't want anything to be stereotypical halloween, I though I was going to be a cat first, but that is too normal. Batman or cat woman is going to be too common now when the dark knight rises is out... I have no idea how the new Bond girl looks like, and zombie is was too common!

Maybe a nice black dress and creepy makeup? Hhm, what is everyone else dressing up like? I need ideas!
