Exclusive to MATCHESFASHION.COM, Roland Mouret's navy Hartnell jumpsuit offers a new formulation of the designer's elegant codes. It’s cut to a plunging V-neck framed with delicate lace, and nips in at the smallest part of the waist for a flattering silhouette. Style it with a metallic bucket bag and let the wide hems flare over a pair of barely-there sandals.
