Schott NYC Melton Wool Naval Peacoat ($220)

As the perfect semi-formal cold season overcoat, the Peacoat has served well from New York to San Francisco. Throw one on over an oxford and sweater and you look dapper as hell, but it served a greater purpose to those who rocked it back in 1723. Men on the sea were constantly fighting the bitter colds with heavy coats made of Pilot cloth—a heavy blue twill material, thus the "P" coat was born.
