EXCLUSIVE AT NET-A-PORTER.COM. Since debuting at Paris Fashion Week in 2011, Australian designer Rebecca Vallance has earned a cult following for her beautiful, feminine pieces. This gown is cut and paneled from fluid crepe to hug your figure. It turns to reveal an open, bow-embellished back and falls to a fluted hem that's lightly stiffened for structure. Balance the vivid coral hue with black or metallic accessories.
