This pairing of a grey open cardigan and black leather skinny jeans is ridiculously stylish and yet it looks functional and apt for anything. Don't know how to finish off? Round off with a pair of black leather ankle boots to kick up the glam factor. In winter, when practicality is essential, it can be easy to settle for a less-than-stylish ensemble in the name of convenience. This ensemble, however, is a stark illustration that you can actually stay snug and remain equally chic during winter.
