Dark brown leather oxford shoes are the most effective way to bring an added touch of class to this ensemble. In the colder months, when warmth is imperative, it can be easy to surrender to a less-than-stylish ensemble in the name of convenience. But this ensemble is a vivid example that you can actually stay comfy and remain equally stylish in the colder months. This one is a stylish and age-appropriate outfit for gents in their forties.
