For an effortlessly classic ensemble, team a tobacco shirt jacket with beige chinos — these two pieces work nicely together. For something more on the cool and casual end to round off this ensemble, complement this outfit with a pair of beige canvas low top sneakers. This combo is a viable option if you're crafting a well-coordinated ensemble for transeasonal weather. And if we're talking casual dressing ideas for 40-something gentlemen, this combo is perfect.
