Such must-haves as a charcoal turtleneck and skinny jeans are an easy way to introduce extra cool into your casual lineup. Complete your getup with a pair of grey snake leather ankle boots for maximum style points. In the colder months, when warmth is a must, it can be easy to surrender to a less-than-stylish outfit in the name of functionality. But this outfit is hard proof that you totally can stay cozy and remain equally chic in the colder months.
