Stella McCartney has reworked the timeless blazer, presenting it as a pure wool dress with a cinched, darted waist that highlights the natural feminine silhouette. Working a classic houndstooth print, it seals with a double-breasted black button fastening, and one of the notched lapels has an additional underlay as an unexpected modern twist. Wear yours bare-legged, or style it as a longline jacket, wearing it with slim pants and high-vamp pumps.
