Leave it to Keira Knightley to put a chic and sophisticated yet completely playful spin on the little black dress. The star was spotted at the UK premiere of Jack Ryan: Shadow Recruit in a peplum number from the Proenza Schouler Spring 2014 collection. While the clean lines of the dress kept things classic, she had a little fun with our (not so secret) favorite part of any outfit: the shoes! Black bow heels lent a girlie touch to her look, which was accented by a bow bracelet and simple studs. Were you a fan of Keira's outfit?
