Margaret Howell

MHL by Margaret Howell's dark-blue loopback-cotton sweatshirt is a year-round item. This failsafe style exudes an uncomplicated cool that's synonymous with the celebrated British designer. Opt for a sophisticated finish and wear it with chinos and lace-up boots, adding a leather satchel for a preppy finish. Shown here with a Jil Sander top, Polo Ralph Lauren trousers, A.P.C. boots and a Paul Smith bag.
