Amp up your cocktail edit with a dose of Saint Laurent's signature insouciance, courtesy of this sleek LBD from the Parisian label's Resort '19 collection. Crafted in Italy from sumptuous black velvet with a lustrous finish, this short style is cut with a plunging V neckline that gives way to a striking cut-out back, complete with shimmering crystal embellishment. Choose a pair of sky-high stilettos to complete your look on a high-octane note.
