Prove that no-one does smart casual men's fashion quite like you do in a charcoal wool blazer and charcoal chinos. If you feel like playing it up a bit now, complement your ensemble with black and white leather derby shoes. Picking out a standout getup can be challenging on its own. Add cold temperatures into the equation, and the whole thing becomes even more difficult. Fear not, this here is your wintry inspo. Wondering how to dress as you reach your 30s? This pairing is the perfect answer.
