In ancient Sinosphere, the most prestigious attire of any person, whether man or woman, in the culture of 華夏 was the ruler’s ceremonial attire, 袞冕. This was the most prestigious religious attire for emperors and kings, and the amount of pearl fringes on one’s crown determined one’s status. Ming dynasty was the last Han period that donned this dress, with a 12-fringed crown, denoting the highest of order in ancient China, while Japan, Korea, and Vietnam all continued this tradition. However, Korea continued to wear 9-fringed crowns to represent its kingship, while Vietnam wore 12-fringed crowns for its emperors and Japan wore 48-fringed crowns for its imperial majesties.
