When it comes to high-octane sophistication, this pairing of an olive shearling coat and blue dress pants never disappoints. Complete this ensemble with brown leather monks for extra style points. In the colder months, when warmth is crucial, it can be easy to surrender to a less-than-stylish ensemble. However, this ensemble is a shining example that you can actually stay toasty and remain stylish at the same time during the colder months. As a guy in his 20s, you'll appreciate this ensemble.
