Marry a dark brown cardigan with a white crew-neck t-shirt for a day-to-day outfit that's full of charm and personality. You can follow a more casual route with footwear by finishing with black leather work boots. In the colder months, when functionality is crucial, it can be easy to surrender to a less-than-stylish look in the name of functionality. However, this look is a striking example that you totally can stay warm and remain stylish in the colder months.
