Nothing gets lost in translation when ScarJo pours herself into this skin-tight leather S.H.I.E.L.D. uniform as the multi-lingual, multi-sexy Agent Natasha Romanoff. The scene where she single-handedly takes out something like 50 armed guards proves just how deadly this Black Widow's bite can be. Blondes may have more fun, but redheads kick more ass, and she can avenge us any day of the week.

In "The Woman in Black," Harry Potter himself (or rather, Daniel Radcliffe) takes on the darker side of the supernatural as he investigates a haunted estate and the dark history that brought one of its former residents back from the grave for revenge.
The "Woman" of the title is kind of a pain in the butt, what with all the murdering and all; but not every similarly clad woman is quite so gloomy. Some of our favorite filmic females have donned a dark look for some memorable roles, no doubt bolstered by the fact that black is slimming.
As Wesley Snipes said in "Passenger 57": "Always bet on black."
