A. OK

If you want something double breasted with a little bit of flare, A. OK is the brand for you. Right now they've got two styles at Oak NYC – one in black and the other in herringbone – both with contrasting wool underneath their collars. The coats are both slim and a little cropped, so you'll want to play close attention to the measurements. Still, they've got style in spades. [$198; oaknyc.com]
