Don't get us wrong -- it's pretty freaking good. But the best ever? Better than Audrey Hepburn in a Givenchy LBD? Marilyn in a cloud of billowy white? Better even than Faye Dunaway in Bonnie and Clyde -- who didn't even make the top ten? (Also notably missing: the many moods of Carrie Fisher.)
Personally, just looking at Atonement alone, that green dress isn't even our favorite costume in the movie. We kind of dug that wet slip after Kiera gets out of the fountain. Meow! Who knew skinny white girl's butt could wiggle like that!
