The best foundation for a neat casual look? A white and black horizontal striped cable sweater with black skinny jeans. Our favorite of a myriad of ways to round off this look is black leather knee high boots. In the winter months, when warmth is essential, it can be easy to settle for a less-than-stylish look in the name of convenience. But this look is a stark illustration that you can actually stay snug and remain equally stylish in the winter months.
