Sang is a ceremonial skirt worn below the waist with the official or ceremonial outfit of the king, the crown prince, the grandson prince regent, and all other government officials. Sang is paired with eui, or upper garment. Eui was black and symbolized the heavens, while sang was red and represented the earth. The sang for the king was made of iridescent silk, with three panels in the front and four panels in the back, totaling seven panels of silk. A string was attached to the waist to be tied, and pleats were attached from top to bottom. Both sides and bottom end of the skirt were outlined with bands. The sang for government officials also had three panels in the front and four panels at the back, and was outlined with blue bands for the official robe and black bands for the ceremonial robe.
