Consider pairing a multi colored houndstooth overcoat with charcoal dress pants for a proper refined ensemble. Go the extra mile and change up your outfit by rounding off with a pair of dark brown suede casual boots. In the winter season, when warmth is paramount, it can be easy to surrender to a less-than-stylish ensemble. This ensemble, however, is a stark illustration that you totally can stay cozy and remain equally stylish during the winter season. All in all, a great example of semi-casual fashion for men in their 20s.
