Having become an unexpected high-fashion hero, the sweater vest is the perfect trans-seasonal layering aid to invest in right now. For styling inspiration, look to street style snaps from the contingent of Scandi-cool girls, plus the collections of Dior, Gucci, Ganni and more.

Whether worn oversized as a solo statement piece on a warmer day, or layered over a shirt and under a coat for when the chill sets in, a sweater vest is no longer the domain of your granddad’s closet — it’s a bona fide styling staple.
