While countless brands are adopting the elegantly disheveled look pioneered by Christopher Bailey a year ago, he’s now steering Burberry Prorsum in a more tailored direction, but with the same offhand attitude. The show started with a gloomy, rainy-day wardrobe of slouchy sportswear including drop-crotch trousers, fine sweaters looped with bondage straps, coated trenches and quilted car coats. Then came suits, which, though they were sharply tailored, looked slept in. Much of the outerwear had wax coatings and plenty of flap pockets. Canvas rucksacks and oversized leather backpacks heightened the rugged, outdoorsman vibe, while Chelsea boots grounded everything in the city. Somewhat out of place was a group of aquatic Burberry Sport jackets in crayon hues. But finally, Bailey treated the audience to delightful tissue-weight, unlined blazers and trenches with puckered seams, and more fine-gauge cashmere sweaters—all in powdery pastels. Their effect was like the sun coming out.
