The court dancing suit, so-called "JeongJae(呈才) suit," has been worn by court dancers on the occasion of the royal court′s feasts or festivals such as auspicious events of a country, court banquets, and parties or receptions for national quests from foreign countries. There are 53 kinds of court dancing suits, ranging from the age of the ancient Three Kingdoms to the period of Chosun Dynasty. The court dancing suits are divided into two styles : DangAk-JeongJae(唐樂呈才) style and HyangAk-feongjae(鄕樂呈才) style, depending on dancing styles. Since the court dancing suits in the age of the ancient Three Kingdoms and Koryo Dynasty have already been studied previously, this study discussed the change of dancing suit styles created in the latter period of Chosun Dynasty, such as YukHwaDae(六花隊), MuSanHyang(舞山香) and ChoonAengJeon(春鶯　), and the thought of Yin-Yang and five elements(陰陽五行思想) that the colors of the court dancing suits imply. The purpose of this study is to understand the thoughts contained in the ancient suits as well as their styles in order to inherit and uphold our traditional culture properly
