A suit looks especially dapper when combined with an olive parka. Bump up the formality of this getup a bit by wearing a pair of black derby shoes. In the winter season, when practicality is top priority, it can be easy to surrender to a less-than-stylish outfit. This outfit, however, is a shining example that you can actually stay snug and remain equally stylish in the winter season. An obvious idea for a 20-something gentleman!
