After a celeb-studded black carpet premiere in Los Angeles, Kristen Stewart jetted off to London to open The Twilight Saga: Breaking Dawn Part 1. She went for a darker look this time around, opting for a black embellished gown by Roberto Cavalli. The piece is taken straight off the designer's spring 2012 runway, and while it was originally shown sheer, the actress had it lined before hitting the premiere. She also made one more styling change—ditching the thick drop waist accent for a thinner leather belt.
