"Po" or "Pho" is a generic term referring to an outer robe or overcoat, which was a common style from the Three Kingdoms of Korea period until the late Joseon period. A belt was used until it was replaced by a ribbon during late Joseon dynasty. "Durumagi" is a variety of "po" that was worn as protection against cold. It had been widely worn as an outer robe over "jeogori" and "baji". It is also called "jumagui", "juchaui", or "juui". A different overcoat derived from Tang dynasty styles was adopted among the elites of Unified Silla and eventually evolved into Gwanbok. "Jokki" () is a type of vest, while "magoja" is an outer jacket. Although "jokki" and "magoja" were created at the end of the Joseon dynasty (1392–1897), directly after which Western culture began to affect Korea, the garments are considered traditional clothing. Each is additionally worn over "jeogori" for warmth and style. "Magoja" clothing was originally styled after the clothing of Manchu people, and was introduced to Korea after Heungseon Daewongun, the father of King Gojong, returned from his political exile in Tianjin in 1887. "Magoja" were derived from the "magwae" he wore in exile because of the cold climate there. Due to its warmth and ease of wear, "magoja" became popular in Korea. It is also called ""deot jeogori"" (literally "an outer "jeogori"") or "magwae". "Magoja" does not have "git", the band of fabric trimming the collar, nor "goreum" (tying strings), unlike "jeogori" and "durumagi" (an overcoat). "Magoja" was originally a male garment but later became unisex. The "magoja" for men has "seop" (, overlapped column on the front) and is longer than women's "magoja", so that both sides are open at the bottom. A "magoja" is made of silk and is adorned with one or two buttons which are usually made from amber. In men's "magoja", buttons are attached to the right side, as opposed to the left as in women's "magoja".
