A biker jacket may not be the first port of call when it comes to warm-weather styling, but thanks to Alexander McQueen, it can now be a mainstay year-round. Italian-crafted in supple lambskin, this outerwear piece is defined by a sleeveless silhouette and ruffles that are heavily influenced by creative director Sarah Burtons preoccupation with shape and volume. Team it with a billowing midi skirt for a striking contrast that refuses to be forgotten.
