Teaming a polo and grey dress pants is a guaranteed way to inject your day-to-day fashion mix with some masculine refinement. Add a different twist to an otherwise mostly dressed-down ensemble by slipping into black leather loafers. Clearly, it's easier to work through a roasting hot summertime day in a light and breezy combination like this one. This combination proves that dressing well as a gent in his forties is not that daunting a task.
