This combination of a black and white crew-neck sweater and black leather leggings is super easy to imitate and so comfortable to rock from dawn till dusk as well! Our favorite of a great number of ways to complement this outfit is lace-up flat boots. In winter, when practicality is key, it can be easy to surrender to a less-than-stylish outfit in the name of practicality. This outfit, however, is a striking illustration that you can actually stay comfy and remain equally stylish in winter.
