We love the way this semi-casual pairing of a green blazer and a white dress shirt immediately makes any man look sharp. You can stick to a more classic route with shoes with a pair of brown woven leather tassel loafers. So if it's a warm hot weather afternoon and you want to look dapper without putting in too much work, this outfit will do the job in next to no time. This one is a nice yet age-appropriate outfit for a guy over 40.
