This pairing of a navy denim jacket and a black crew-neck t-shirt is very easy to imitate and so comfortable to rock as well! If you want to feel a bit fancier now, finish with a pair of black leather casual boots. In winter, when functionality is the priority, it can be easy to settle for a less-than-stylish outfit in the name of practicality. However, this outfit is a striking example that you can actually stay snug and remain stylish at the same time in winter.
