This relaxed combination of a black wool turtleneck and black jeans is extremely easy to pull together without a second thought, helping you look sharp and prepared for anything without spending too much time digging through your closet. Complement this ensemble with a pair of white canvas low top sneakers and ta-da: this look is complete. This look is a bright example that you don't have to give up style for functionality during winter. After all, when do you dress casually if not in your 20s?
