The association of the Mamianqun (马面裙) with high-class courtesans seems to be a misunderstanding. While it's true that courtesans in some eras might have worn fashionable clothing, the Mamianqun was a common style worn by women of various social classes during the Ming and Qing dynasties. It was not exclusive to courtesans, nor was its primary purpose to provide 'emotional value' to men. The design was rooted in functionality and aesthetics for a wide range of women.
