The uncertain period between the last of summer’s humidity and the onslaught of fall’s bracing cold presents something of a wardrobe conundrum. You’re sick of your flimsy warm-weather clothes, but it’s still a bit early to unpack your knits. In the meantime, this heather-gray cotton jacket can span the changing seasons. The asymmetrical lapels can be fastened in several ways depending on your outfit, and a buckle cinches in back to flatter your shape. Wear it with a tee on breezy days, or layer it over a slim hoodie or cardigan when brisk weather arrives in earnest.
