A brown blazer and khaki dress pants are an elegant combination that every stylish guy should have in his wardrobe. If you're clueless about how to finish, complete your outfit with dark brown leather loafers. As you can see here, this combo is a really smart choice, especially for in-between weather, when the mercury is starting to drop. A good pairing to make you a well-dressed man in his 40s, rather than just a man in his 40s.
