How to wear women’s winter jumpers and cardigans
Women's winter jumpers and cardigans are the layer that decides how heavy a coat needs to be. At this weight a jumper is warm enough to be the only thing under an overcoat, which keeps the outer line clean; worn alone indoors, the round neck sits high enough to take a scarf without crowding it. A cardigan left open over a plain shirt reads more easily than one fastened, which is why the placket is made fine enough to sit flat either way.
Take the size you normally take. The cut is close rather than tight, with room across the shoulder and a sleeve that finishes at the wrist bone. Wash by hand below 30°C in a wool detergent, press the water out rather than wringing, and dry flat away from direct heat. Fold rather than hang, so the shoulders keep their shape through the season.
