One of the best parts of having a roommate is having an instantly doubled wardrobe. But if "The Roommate" stars Minka Kelly and Leighton Meester lived together, we don't think they'd be digging in each other's closets that much. These two lovely ladies may look like sisters and are, at times, virtually impossible to tell apart, but they have very different styles: Leighton is experimental, while Minka is much more reserved. In this all-new Fashion Face-Off, we take a look at their past fashion picks, and you can vote on which look you like best.
At the premiere of "The Roommate," Minka wore a long-sleeved crinkle silk chiffon J. Mendel dress in a pale marble hue, while Leighton opted for a black Michael Kors gown with leather top and cut-out sides.
