A commander’s uniform is a military uniform worn in the Joseon Dynasty, particularly referring to those following the reigns of King Jeongjo and King Sunjo. A commander’s uniform consisted of a military hat, outer blouse, vest, waist belt, waistband, and wooden-sole boots. The outer blouse resembles an ordinary durumagi, or outer coat, but the central line on the back and the patches below the armpits were either left open or sewn shut. The sleeves and the body were different in color, and the sleeves were usually red while the body was scarlet. During the period of King Sukjong, the color of the body varied such as green, wine, black, or pink. The uniform was accompanied by a pocket to store a round wooden plate signifying military mobilization orders, an arrow holder and a sword on the shoulder, and a whip in one hand. A commander’s uniform was used as an undergarment beneath the outer armor, then later became the official military uniform after the Japanese Invasion of Korea in 1592.
