Marry a dark brown shawl cardigan with navy chinos and be prepared to be treated like a men's fashion maven. Infuse this look with an air of class with a pair of dark brown leather brogues. So so as you can see, it's a knockout, not to mention season-appropriate, ensemble to have in your transitional closet. As a gentleman in his thirties, you probably want to start dressing like an adult. That's when combos like this are a safe bet.
