You'll be surprised at how extremely easy it is to get dressed this way. Just a brown overcoat and a brown plaid blazer. Our favorite of an infinite number of ways to round off this outfit is a pair of dark brown suede chelsea boots. Rest assured, this getup will keep you cozy as well as looking dapper in this transitional weather. As a 30-year-old guy, you probably want to start dressing with more refinement. That's when inspo like this comes in very useful.
