Pair a navy overcoat with white chinos to create an interesting and put together ensemble. Brown leather casual boots are a wonderful idea to finish off your ensemble. During winter, when warmth is crucial, it can be easy to settle for a less-than-stylish outfit. This outfit, however, is a striking example that you can actually stay comfortable and remain stylish at the same time in winter. Also, it's a perfect outfit if you want to blend in with a professional crowd.
