Clare Waight Keller's FW13 Chloé show was her best yet. "It's about girls who emerge from uniform," she said afterwards, and this grown-up navy and blue crepe shift dress proves the point. The optional patchwork jacket is what makes it special: cut from chiffon and twill and cropped to enlist movement as you walk, it gives this elegant style modern edge. Dress: Zipped back, hook fastening. Side slit pockets. Fully lined. Top: Zipped back, hook and button fastenings. Zipped cuffs, intentionally frayed trims. 65% Polyester, 18% Silk, 17% Viscose. Material II: 55% Acetate, 45% Viscose. Material III: 100% Silk. Dry clean.
