EXCLUSIVE AT NET-A-PORTER.COM. The secret to Roland Mouret's flawlessly tailored, curve-enhancing dresses is draping fabric directly onto the body instead of drawing sketches. This 'Lely' gown is crafted from stretch-crepe with the label's signature asymmetric neckline and deftly placed, contouring seams. It has a cutout back and ruffled split hem to reveal a hint of skin. Offset the rich purple hue with black or metallic accessories.
