Effortlessly blurring the line between cool and off-duty, this combination of a blue long sleeve shirt and a white crew-neck t-shirt can easily become one of your favorites. Bring a hint of class to your outfit by rounding off with black leather derby shoes. During winter, when warmth is the priority, it can be easy to settle for a less-than-stylish getup in the name of convenience. But this getup is a vivid example that you totally can stay toasty and remain stylish in winter. This is a nice yet mature combination for young guys.
