For a look that's sophisticated and Kingsman-worthy, pair a charcoal waistcoat with navy jeans. Complement your ensemble with a pair of brown leather chelsea boots et voila, the getup is complete. During the winter season, when practicality is critical, it can be easy to settle for a less-than-stylish look in the name of convenience. However, this look is a shining example that you can actually stay comfortable and remain equally stylish during the winter season. A perfect combo to make you a sharp-dressed gentleman in his 40s, rather than just a gentleman in his 40s.
