Traditional cardigan design calls for two patch pockets at the waist, and frankly nothing good has ever come of that—they add un-flattering midsection bulk, they inevitably sag and look terrible, and you weren't going to stick anything in them regardless. So sleeker pocketless cardigans are a welcome trend, looking better as an outer layer and working nicely under coats and jackets. Shown: Uniqlo, merino, $40. Brooks Brothers, lambswool, $168. Dunhill, cashmere from Mongolian goats that apparently dined on nothing but exotic flowers and royal jasmine tea their entire lives, $650.
