We love the way this classic and casual pairing of a charcoal blazer and navy jeans immediately makes you look stylish. You can get a little creative on the shoe front and dress up your outfit by finishing with black leather derby shoes. Dressing warmly is the trick to surviving cold temps, but this look is a clear example that you can accomplish this with style. As you're maturing from your 20s to your 30s, you want to start dressing like a grown man. In this case, inspo like this comes in useful.
