Work a layered look with sleeveless jackets in denim, leather and fur, or keep cosy on cold-weather days in a classic Moncler padded gilet. Tailored singlets and tux-style waistcoats look sharp teamed with skinny trousers, look to tailoring favourites Stella McCartney, Maison Martin Margiela and Ann Demeulemeester for the most fashion-forward versions.
