Woman in traditional Chinese Hanfu.
She is wearing a Ruqun/襦裙 from Zhuliguan/竹里馆. Its design is inspired by the famous Chinese scroll painting The Night Revels of Han Xizai (segment shown below). Many Hanfu designers
have been inspired to recreate the clothing depicted in the painting. In this case, Zhuliguan recreated the Ruqun with the blue top, white skirt, and light green sash.
