Her nude J.Mendel was pretty but this is straight up fun. Kristen Stewart hit the London red carpet for her new flick, New Moon. While most are focusing on her chemistry with Robert, I'm zooming in on her Proenza Schouler Spring '10 look. It's youthful, spunky, and so is Kristen. I only wish the top were a tad more fitted. I loved the scuba sandals on the catwalk, but Kristen's black patent pumps work as well. What do you think of Kristen in Proenza?
