Teaming a light blue long sleeve shirt and khaki dress pants is a fail-safe way to infuse your daily outfit choices with some manly refinement. Play down the formality of this ensemble by finishing off with brown athletic shoes. On not-so-chilly afternoons, you can rock a version of this easy-to-transition look and look absolutely awesome. When it comes to dressing ideas for over-40 gents, this combo is a good look on almost any gentleman.
