The mix-and-match capabilities of a charcoal cowl-neck sweater and skinny jeans guarantee they'll always be on regular rotation in your closet. To give this ensemble a more sophisticated touch, complement this outfit with a pair of black cutout leather ankle boots. During the winter season, when practicality is above all, it can be easy to surrender to a less-than-stylish ensemble. But this ensemble is a bright example that you totally can stay warm and remain equally stylish in the winter season.
