A dark green short sleeve shirt and a crew-neck t-shirt are absolute menswear staples if you're crafting a casual closet that matches up to the highest style standards. When this getup appears too classic, dress it down by slipping into white and black athletic shoes. This outfit is a viable option if you're piecing together a well-coordinated ensemble for transeasonal weather. Outfit inspo like this will help you stay incredibly fashionable even well into your 50s.
