For an ensemble that's street-style-worthy and effortlessly neat, wear a camel overcoat and khaki chinos. Play down the formality of your outfit by rocking a pair of white and black athletic shoes. During winter, when functionality is top priority, it can be easy to settle for a less-than-stylish getup. This getup, however, is a practical illustration that you totally can stay warm and remain stylish during winter. When it comes to fashion for 20-year-old gents, this ensemble is ideal.
