peacoat
A type of outer jacket or coat, generally made heavy wool. Pea coats are characterized by short length, broad lapels, double-breasted fronts, often large wooden, metal or plastic buttons, three or four in two rows, and vertical or slash pockets. References to the pea jacket appear in American newspapers at least as early as the 1720s, and modern renditions still maintain the original design and composition.
It was originally worn (navy blue colour) by sailors of European and later American navies. A pea coat that extends to the thighs is called "bridge coat", and is a uniform exclusively for officers and military chief petty officers. Only officers wear ones with epaulettes.
Peacoat is mostly a misnomer, by the danbooru coat guidelines of coat and jacket. On danbooru a jacket is from waist to hip length, and coat is thigh or lower. Peacoats are characterized by their short length, reaching the hips or crotch, which would be considered a jacket.
