Fashionable and functional, this combination of a grey crew-neck t-shirt and grey skinny jeans will provide you with excellent styling opportunities. Finishing with dark brown leather casual boots is a surefire way to breathe an extra dose of class into your outfit. In the winter months, when comfort is paramount, it can be easy to settle for a less-than-stylish outfit in the name of practicality. This outfit, however, is hard proof that you can actually stay toasty and remain stylish during the winter months.
