If you're looking for an off-duty yet on-trend getup, pair a shirt jacket with khaki vertical striped chinos. Athletic shoes will give a laid-back vibe to an otherwise sober outfit. In the colder months, when warmth is the priority, it can be easy to surrender to a less-than-stylish ensemble. But this ensemble is a good illustration that you totally can stay warm and remain stylish in the colder months. This combination should prompt anyone who had doubts about sleeker ensembles in his twenties.
