It was the battle of the jumpsuits at this years Vanity Fair Young Hollywood party. Supermodel Suki Waterhouse was stunning in a sheer black, cleavage baring number that put her catwalk ready figure on display. The edgy blonde beauty, who is of course girlfriend to Hollywood heavyweight Bradley Cooper, finished her look with a black chocker and her trademark messy waves. Attempting to steal her limelight was the sultry Emily Ratajkowski who went for a tailored purple jumpsuit with sharp cut-outs. The Gone Girl star's figure, which we all saw a lot of in the Blurred Lines video, was perfectly complimented by the chic fitted ensemble.
