There's a reason Kylie Jenner and Cara Delevingne choose to wear Alexandre Vauthier's dresses on the red carpet - each design is expertly draped and gathered to frame your figure so beautifully. Cut from lustrous royal-blue silk-satin with a hint of stretch, this gown has ruffles cascading from the halterneck right down to the fluted split hem. Wear your hair up to showcase the open back.
