For a neat and relaxed look, try pairing a khaki military jacket with a white crew-neck t-shirt — these items go really well together. A pair of white leather low top sneakers is a savvy pick to complement your outfit. Keep this combo in your front hall closet when spring sets it, and we promise you'll save a ton of time getting dressed on more than one morning. This pairing is a shining example gentlemen over 40 can very well slay in the fashion department.
