Katie Holmes attended the 16th Annual Women in Hollywood Tribute sponsored by ELLE at the Beverly Hilton Hotel last night and revealed a little more than she may have intended.  She arrived solo because hubby Tom Cruise is currently filming in Boston.

Holmes hit the red carpet wearing a sheer black top over an Alaia skirt.  Her shirt choice clearly showcased her black bra beneath the see-through fabric.   See more red carpet photos here.

So was it intentional?  We think not.  You?
