qing guanmao
Qing Guanmao (清代官帽) is a hat that was worn by Chinese officials during the Qing dynasty.
It's a round hat with a thick (usually black) velvet trim and a brightly colored cone-shaped top with a small button at the peak that can vary in size. A ribbon or something similar can be attached to the top as well. Very often worn by jiangshi, in which case an ofuda is usually attached to the front.
Some characters usually seen wearing a Qing Guanmao are Lei Lei, Qiqi, Mei in her Jiangshi skin, and Shuten Douji in her Heroic Spirit Festival outfit.
