This navy blue and black Helen Lawrence contrast stripe jumper proves to be the perfect partner for cold-weather layering thanks to its 3/4 length sleeves. It has been crafted from a luxuriously warm mohair-wool blend, boasting a round neckline and ribbed slim-fitting silhouette. The eye-catching piece is finished off with a contrasting yellow paint stripe across the torso and around the back for an added burst of energy (who needs a double espresso, when you've got Helen). Pair your sumptuous knit with Maison Margiela trousers and Rick Owens trainers next time you go for an outdoor screening in the park.
