Buddhism is one of mainstream of spiritual culture in Korea, and Buddhist ideology and doctrine are inherent in the costume of Buddhist monks who uphold it. Today each Buddhist sect adheres to its own Buddhist costume as distinct from others, but the original form doesn"t considerably deviate from tradition. Simply put, current Buddhist costume is governed by Buddhist ceremonies and purposes unlike the previous one for hierarchical distinction of Buddhist priests in the Goryeo era when Buddhism flourished. This study looked at the composition and characteristics of red robes of Buddhist priests based upon the portraits of high priests of the late Joseon era and five red robes of Buddhist priests from the 19th century through the mid-20th century possessed by Seokjuson Museum, Dankook University. Moreover, it produced the red robes of Buddhist priests using cutting and sewing techniques which are even now accepted. According to the portraits of high priests and robe relics, red robes of Buddhist priests seem to have persisted until now after undergoing the late Joseon era and the modern period. In addition, such production of robes of Buddhist priests offers symbolic implications for the whole process ranging from cutting to completion rather than a simple sewing activity for finishing the production of clothing, thus it can be constructed as a holy relic.
