qing quanmao
The Qing Guanmao (清代官帽) is a hat that was worn by Chinese officials during the Qing dynasty.
It is 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, referencing how Qing-era officials were viewed as bloodthirsty creatures with little regard for humanity, 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.
