This classic and casual combo of a navy overcoat and dark brown chinos is extremely easy to put together in seconds time, helping you look amazing and prepared for anything without spending too much time digging through your closet. Take this look in a dressier direction by slipping into a pair of dark brown leather loafers. During winter, when functionality is everything, it can be easy to surrender to a less-than-stylish ensemble in the name of functionality. However, this ensemble is a striking illustration that you totally can stay comfortable and remain equally stylish in winter. If you're wondering what you should wear as a 40-year-old gentleman, this outfit is a good source of inspiration.
