Fashionable and functional, this laid-back combination of a navy duffle coat and a white crew-neck t-shirt provides with variety. Not sure how to finish off? Add a pair of white and black leather low top sneakers to the equation for a more relaxed touch. During winter, when functionality is prized, it can be easy to surrender to a less-than-stylish ensemble in the name of functionality. This ensemble, however, is a good illustration that you totally can stay cozy and remain equally stylish during winter.
