For an ensemble that's city-style-worthy and effortlessly classy, rock an overcoat with a navy gilet. Dark brown suede casual boots will bring a fun touch to an otherwise traditional look. In the winter season, when warmth is essential, it can be easy to surrender to a less-than-stylish getup in the name of convenience. However, this getup is a good illustration that you can actually stay warm and remain equally stylish during the winter season.
