Roland Mouret's 'Cheveley' gown is part of the label's Pre-Fall '17 collection that marks the house's 20th anniversary - "for my 20th year of designing, I want to open doors and discover new categories to push in a specific direction," he says. Cut from structured crepe in a royal-blue hue that evokes the designer's memories of the sea in the South of France, this piece has fluttering cape-effect sleeves and straps that cross over to frame your shoulders.

Shown here with: Bottega Veneta Clutch, Jimmy Choo Sandals, Miu Miu Earrings, Jennifer Fisher Rings.
