Sienna Miller
Well, 12 hours later, we're still standing in ovation for both the bare-faced babe and Sienna Miller's stylist, Cher Coulter, for giving us a dose of funky-chic in the form of Erdem separates. Adding to our uncharted-territory elation, she rocked three Van Cleef & Arpels earrings on one side, while going au natural on the other. The appliqué florals, white-lace base, and risk-taking attitude are exactly why she was The Girl of the evening, despite being shafted of the actual trophy.
