[1]: 120  It also goes by the names jumagui (주막의; 周莫衣), juchaui (주차의; 周遮衣), or juui (주의; 周衣),[2] The origin of durumagi traces back to at least the Three Kingdoms of Korea, where it originated from a long coat worn by the northern Chinese to fend off cold weather in ancient times.

The origin of durumagi, the long outer coat worn over a jeogori, goes back to the Goguryeo period.

The durumagi emanates form the long coat worn by northern Chinese to fend off cold weather in ancient times.

[3]However, what is now known as the durumagi is part of the indigenous attire of the Korean people:[10] Based on the Goguryeo mural paintings found near Pyeongyang, such as the early 5th century murals from Gamsinchong (龕神塚), the ancient durumagi worn by the owner of Gamsinchong tomb was red (or purple) in colour:[11]: 16 [The tomb of the owner of Gamsinchong Tomb] is sitting on a flat bench under a red curtain, in a purple durumagi (a traditional Korean men’s overcoat) with both hands held inside the wide sleeves on his chest.

[12] Not only was the waist belt changed into a goreum, the traditional po's short length and wide sleeves were lengthened and narrowed to the style of the Mongolian coat, xurumakci, of which the name durumagi is said to be derived.

[14] However, this law was met with much resistance and it was only until ten years later, after the Gabo Reform of 1894, that the durumagi became common as formal attire.

[16] The durumagi is still considered an important part of traditional attire for formal occasions,[17] but a variety of colours and designs are being used.
