Go for a tobacco blazer and a light blue chambray dress shirt for a neat polished look. All you need now is a pair of burgundy leather derby shoes. During the winter months, when functionality is prized, it can be easy to surrender to a less-than-stylish look in the name of practicality. However, this look is a good illustration that you totally can stay snug and remain equally stylish in the winter months. Certainly a foolproof choice when it comes to style for 30-something men.
