the problem of 'traditional dress' in class societies is you're inevitably dressing as the aristocrats who shackled your great-great-great grandparents

like sure Ming mandarins were drippy as fuck, and confucian top-knots look very cool but either looking like a servant of the emperor or an adherent of the patriarchal tradition is not something a representative of an egalitarian party should be doing in an official capacity. this is why zhongshan suits and short hair were adopted

if this feels like a chauvinistic position i'll remind you western liberal government officials also do not wear 'traditional' dress. the common ancestor of european formal wear is based squarely in the styles developed during the French Revolution. though recuperated & much elaborated on in the following centuries, the western business suit (that name's very much a reminder of the kind of class society we're under lol) is the consciously created revolutionary garb of the ascendant bourgeois---the real chauvinism is how western communists failed to bring a new style into being to inaugurate socialist revolution SMDH Stalin ya shudda brought back skirts or something
