Putting together a green parka with grey chinos is a smart pick for a casual yet sharp ensemble. Don't know how to complement your ensemble? Wear desert boots to ramp it up. In the colder months, when warmth is top priority, it can be easy to settle for a less-than-stylish outfit. This outfit, however, is a striking example that you totally can stay cozy and remain equally stylish in the colder months. Overall, a perfect example of casual style for gents in their 50s.
