Jennifer Lawrence and Robert Pattinson walk the Cannes Film Festival red carpet for the premiere of Lynne Ramsay's "Die, My Love."

Robert Pattinson and Jennifer Lawrence laughed off a joint wardrobe malfunction during the Cannes Film Festival premiere of their film, 'Die, My Love.'

Lawrence’s dress is a modern day version that was first seen in 1949. It is named for the composer Francis Poulenc. The strapless dress is pleated, featuring scalloped layers in tiers. The design is belted, pulling the waist tight.
