If we were forced at gunpoint to choose 3 models to take home (would be an amazing situation, no?), Lara Stone would make the top three. She is simultaneously quirky and sexy, and it seems Calvin Klein knows to keep a good woman when it has one, since she is one of the few models who remains the face of a label for more than a season or two. Stone poses for a Calvin Klein's black and white Spring 2012 campaign shot by Mert & Marcus.
