For a look that's worthy of a modern style-savvy gentleman and effortlessly smart, pair a tan cotton blazer with dark brown plaid chinos. Brown suede loafers are the most effective way to inject an added touch of refinement into this look. So as you can see, this combination is a really good choice, especially for unpredictable fall weather, when the temps are dropping. This outfit shows that cracking the fashion code as a 30-something Millennial gentleman is quite manageable.
