We're loving the way this combo of a dark brown overcoat and a dress shirt instantly makes any guy look polished and sharp. And if you wish to immediately dial down this outfit with footwear, add brown suede casual boots to the equation. Picking out a well-coordinated outfit can be a bit of a juggling act on its own. Add cold temperatures into the equation, and the whole thing becomes even more difficult. Fear not, this here is your wintry style inspo. If you want people to see maturity in you as a 20-year-old man, an outfit like this is a foolproof option.
