The concept of sweater dressing isn't a new phenomenon, but it's one that 3.1 Phillip Lim continues to reenergise. This crackle-coated fleece-lined sweatshirt is part of a Pre-AW14 collection inspired by 1990s rave culture, and has elements of the era's oversized, sporty aesthetic. Slip it on with slick pencil skirts or tailoring, making sure to roll up the sleeves for added nonchalance.
