"Durumagi", which was previously worn underneath "jungchimak" and was basically a house dress, replaced "jungchimak" as the formal outwear for "yangban" men. "Durumagi" differs from its predecessor in that it has tighter sleeves and does not have splits on either sides or back. It is also slightly shorter in length. Men's hanbok has remained relatively the same since the adoption of "durumagi". In 1884, the Gapsin Dress Reform took place. Under the 1884's decree of King Gojong, only narrow-sleeves traditional overcoat were permitted; as such, all Koreans, regardless of their social class, their age and their gender started to wear the durumagi or "chaksuui" or "ju-ui" (周衣).
