Pairing a suit and a black crew-neck sweater is a surefire way to infuse your wardrobe with some laid-back refinement. For a trendy hi-low mix, introduce a pair of olive suede desert boots to this ensemble. During the winter season, when warmth is everything, it can be easy to surrender to a less-than-stylish ensemble. However, this ensemble is a good illustration that you can actually stay comfortable and remain equally stylish during the winter season.
