If you're going to dress-up, then go the whole hog. Dan here is wearing a three-piece suit and has all the accessories; the pocket square, the brogues, the camel overcoat and the tie-pin. The colour of the suit is unusual but works well in both cold and warmer weather. It's classic, cliché I know, but the blue shirt and wool tie makes it contemporary.
