tteoguji
Traditional Korean headdress worn during the Joseon Dynasty. Worn by queens and crown princesses for formal attire. It resembles two large hair rings, of which flop over the scalp diagonally.
It is one of many styles of carved-wood wig ornaments in Korea, called gache (加髢).
It was usually made from paulownia, a lightweight wood, and engraved with braid patterns.
