This ceremonial robe worn by Yu Gil-jun (1856–1914), a writer, politician, independence activist and thinker of the Korean Enlightenment during Korea’s late Joseon Dynasty, is an invaluable material that illustrates the Korean government’s effort to establish an independent clothing system by simplifying the traditional style of ceremonial costume. The robe is highly regarded among historians as it was worn by a historic figure and is notable for incorporating certain western elements, including buttons, into traditional ceremonial clothing.
