Such must-haves as a white and black crew-neck sweater and navy skinny jeans are the perfect way to introduce effortless cool into your casual styling lineup. Showcase your elegant side by finishing off with a pair of brogue boots. In the winter months, when practicality is essential, it can be easy to settle for a less-than-stylish ensemble in the name of functionality. This ensemble, however, is a shining example that you can actually stay comfortable and remain equally stylish during the winter months.
