甲午改革
During the Joseon Dynasty, the "durumagi" was less worn as an overcoat but more of a housecoat for the noble class, whereas it was worn outdoors by the commoners. In 1884, King Gojong promulgated the unification of clothing for all social classes through reform laws. 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.
