This combo of an overcoat and a dark green polo looks dapper, but it's super easy to create. For a more sophisticated aesthetic, why not complete your outfit with a pair of brown leather oxford shoes? An amazing example of functional fashion, this ensemble must be in your front hall closet this winter season. As you get into your 30s, you want to start dressing in a dressier manner. If that's the case, inspiration like this comes in very useful.
