For a laid-back and cool getup, try pairing a mustard crew-neck t-shirt with navy gingham chinos — these items fit well together. Casual boots will bring an air of class to an otherwise utilitarian ensemble. Keep this outfit in mind when warmer days are here, and we promise you'll save time brainstorming for what to wear on more than one occasion. A nice, less conservative outfit for a 40-something gent.
