For a look that's street-style-worthy and casually sleek, try pairing a suit with an olive parka. To give your look a more sophisticated spin, complement your ensemble with a pair of black derby shoes. During winter, when practicality is essential, it can be easy to surrender to a less-than-stylish ensemble. But this ensemble is a clear example that you totally can stay snug and remain equally stylish in winter. This combination is a great inspo to anyone who had doubts about sleeker style in his twenties.
