This semi-casual pairing of a navy shirt jacket and khaki chinos is super easy to put together in next to no time, helping you look sharp and prepared for anything without spending a ton of time digging through your wardrobe. Finishing with a pair of navy canvas slip-on sneakers is a fail-safe way to inject a touch of stylish casualness into your outfit. This pairing is a huge inspiration to anyone who was doubtful about wearing casual outfits as a 40-year-old gent.
