This combo of a navy plaid blazer and a light blue dress shirt is really sharp and provides instant polish. Our favorite of a variety of ways to complete this ensemble is with black suede loafers. During the colder months, when functionality is everything, it can be easy to surrender to a less-than-stylish outfit in the name of functionality. However, this outfit is a good illustration that you totally can stay snug and remain equally stylish in the colder months.
