For a relaxed ensemble, make a white long sleeve shirt and white chinos your outfit choice — these two items play really nice together. Introduce a pair of brown leather low top sneakers to the equation to inject a touch of stylish casualness into this getup. Come super hot summer days you're looking for a look to keep you cool and stylish –– this outfit is just what you need. And if we're talking casualwear for men over 40, this combo looks great on almost any guy.
