When it comes to high-octane refinement, this combination of a cardigan and a waistcoat is the ultimate style. During the colder months, when warmth is above all, it can be easy to settle for a less-than-stylish outfit in the name of functionality. This outfit, however, is a striking example that you can actually stay cozy and remain equally stylish during the colder months. Rock this ensemble to create a more conservative look as a young man.
