(; also written with the characters《》; ), was also called (), (), (), (), and (), is a type of (upper garment) for women in , the Korean traditional clothing, which was worn for ceremonial occasions (e.g. for minor ceremonies in the palace as soryebok (小禮服)) in the palace during the Joseon dynasty. It was typically a garment item reserved for the upper class and commoners of this period would rarely see anyone in this garment. It was worn as a simple official outfit or for small national ceremonies while court ladies wore it as a daily garment. Origins It is currently believed the Dangui originated from jangjeogori (장저고리; long jeogori), which was worn before the early Joseon Dynasty as formal wear. The scholars of the late Joseon Dynasty, such as Bak Gyusu who wrote the Geoga japbokgo (거가잡복고 居家雜服攷), a history of Korean clothing, in 1841, believed that the Dangui originated from China and may have dated back to the time when the Chinese clothing system was introduced to Korea between 57 BC and 668 AD, during the Three Kingdoms period of Korea: This belief was due to the use of the Chinese character《》; this character could either refer to the Tang (唐) dynasty or indicate a "Chinese" (唐) product introduced from China; but, in this context, the scholars had assumed that it referred to the Tang dynasty. However, the claim that the dangui dates back to the Tang dynasty is currently judged as being erroneous, considering that the clothing characteristics of Dangui appeared in the middle of the 17th century according to the excavation of related relics. It is also noted that it is only in the 17th century that the term dangui first appeared in literature. Whether the late Joseon theory on the origins of the dangui is probable or not, it is certain that was worn during the Joseon period, based on historical documents and remains.
