We love how this combination of a navy waistcoat and white chinos instantly makes you look classy and smart. Hesitant about how to finish? Introduce brown leather casual boots to the mix to switch things up. During the winter season, when warmth is paramount, it can be easy to settle for a less-than-stylish ensemble. This ensemble, however, is a striking illustration that you totally can stay toasty and remain stylish at the same time in the winter season.
