Wear a polo neck sweater and white chinos if you're aiming for a proper, on-trend ensemble. Bump up the dressiness of your outfit a bit by finishing off with tan loafers. Keep this combination in your front hall wardrobe when warmer days are here, and rest assured, you'll save a lot of time getting ready on more than one morning. A fail-safe option for gentlemen in their 20s scouting for a more professional look.
