To give this outfit a smarter vibe, complement your ensemble with a pair of brown suede chelsea boots. With springtime approaching, it's time to sport simple and dapper combos, just like this. This ensemble is the perfect answer to the question of how to dress age-appropriately as you head into your 30s.
