The ideal foundation for casually sleek menswear style? A dark brown overcoat with jeans. Feeling bold today? Mix things up by rocking a pair of dark brown leather derby shoes. During winter, when warmth is prized, it can be easy to settle for a less-than-stylish outfit in the name of practicality. But this outfit is a bright example that you can actually stay cozy and remain equally stylish during winter. Combos like this have a sophisticated air that befit gents over 30 really well.
