We're loving the way this combo of a beige overcoat and a blue suit immediately makes a man look smart and refined. Complete this outfit with tan suede double monks to avoid looking too formal. This combination is a vivid example that you don't have to give up style for comfort during winter. As you go into your 30s, you want to start dressing in a classier manner. If that's the case, outfits like this are perfect as inspiration.
