At the Cannes premiere of This Must Be The Place, legendary catwalker Claudia Schiffer and runway stunner Anja Rubik went head-to-head on the red carpet, both clad in sexy black gowns — and both with little left to the imagination. Claudia sported a lace bustier Dolce & Gabbana gown, accessorizing with layered diamond necklaces and a pair of black pumps. Anja's dress may have been full-length and long-sleeved, but it wasn't exactly modest. The Emilio Pucci gown was covered in sequins, and featured an ornate pattern made up of tiny holes. Both models looked gorgeous — but who did black peekaboo best?
