A white and black crew-neck sweater and black leather skinny pants make for the ultimate cool casual getup. Our favorite of an endless number of ways to finish this look is with pumps. In the winter months, when practicality is above all, it can be easy to settle for a less-than-stylish outfit. This outfit, however, is a striking example that you can actually stay comfy and remain totaly stylish at the same time during the winter months.
