The formula for effortlessly smart menswear style? A grey shearling jacket with a white wool turtleneck. In the shoe department, go for something on the casual end of the spectrum and complete your outfit with black leather high top sneakers. During the colder months, when warmth is above all, it can be easy to surrender to a less-than-stylish getup in the name of functionality. This getup, however, is hard proof that you totally can stay toasty and remain stylish at the same time during the colder months.
