If you're hunting for a casual but also seriously stylish getup, choose a blue denim jacket and khaki chinos. Kick up the formality of your outfit a bit by slipping into dark brown leather casual boots. In winter, when warmth is everything, it can be easy to surrender to a less-than-stylish outfit in the name of convenience. However, this outfit is a good illustration that you totally can stay warm and remain stylish at the same time during winter.
