Jeokui was a ceremonial robe originally worn by Empress of China. During the late Goryeo Dynasty, the Queen started to wear it as a ceremonial dress. Pyeseul is an ornament designed to cover the knees since it hangs down vertically when worn with jobok (court dress) or jebok (ritual dress).
These are paper patterns of the pyeseul and jeokui, which were made in the real size, shape, and pattern by connecting several layers of paper. In the jeokui paper pattern, two pairs of pheasant were drawn face-to-face on pale blue background, with the flowers drawn with four colors between the pheasants. The edge of the clothes was made using thick red paper, with patterns of dragon and clouds drawn. For the pyeseul paper pattern, it is divided into three parts, with a pair of pheasants drawn on each part. A dragon was drawn at the edge of each part.
A jeokui made with this pattern is preserved at the museum of Sejong University. These paper patterns are regarded as important articles in reproducing the jeokui and pyeseul of the late Joseon Dynasty.
