CANNES, May 20, 2014/ — At the premiere of “Deux Jours, Une Nuit” at the Cannes Film Festival, Alessandra Ambrosio chose to wear Versace. The supermodel was beyond breathtaking in a look from Atelier Versace Spring/Summer 2014 – she wore a stunning white, one-sleeve gown fully embroidered with Swarovski crystals, with delicately beaded draping over a fitted bodice, with a thigh-high slit at the left.
