Sexy, jazzy showtunes?

Hi all! I'm auditioning for Cabaret. I need to find an audition song, and everybody and their mother is doing something from Chicago or Sweet Charity. I need something else. It doesn't need to be from a musical but nothing poppy- it needs to be something jazzy. Preferably uptempo. Also- at first impression I'm seen as a very sweet and innocent girl, so I'd like to audition with something that can prove I'm comfortable with letting my sexy, flirty side out. Any ideas or suggestions would be VERY appreciated. Thanks!
