Best Bet: Surface to Air Merino Cardigan

A smart winter wardrobe calls for versatile, cozy layers that don’t add extra bulk. Surface to Air’s fall collection is currently 40 percent off, including this luxuriously soft cardigan in cherry-red or gray. The sweater strikes a sweet balance, pairing menswear-inspired leather elbow patches and a slightly longer fit with silky, extra-fine merino wool. Despite the feathery feel, it still looks sharp; the light knit doesn’t swallow your shape like saggy boyfriend cardigans.

Long merino cardigan, $180 (originally $300) at Surface to Air or online.
