Marry a navy overcoat with a brown suit if you're aiming for a neat, smart outfit. Give a more informal twist to an otherwise mostly classic outfit by rounding off with a pair of dark brown leather chelsea boots. Dressing warmly is the key to surviving extra cold temps, but this ensemble is a bright example that you can do it with style. Wondering what clothing is appropriate as you get into your 40s? This combo is the perfect answer.
