You'll be surprised at how easy it is for any guy to pull together a casual outfit like this. Just an olive turtleneck worn with jeans. When this ensemble appears too perfect, dress it down by sporting a pair of charcoal athletic shoes. During the winter season, when warmth is a must, it can be easy to surrender to a less-than-stylish ensemble in the name of functionality. This ensemble, however, is a bright example that you can actually stay comfy and remain stylish at the same time in the winter season. Guys who are curious how to pull off edgy off-duty style as you move through your 20s, you have your answer.
