I come from an immigrant family living in the US and we have a cheongsam that's passed down to each bride-to-be to wear on her wedding day. Living in predominately white cultures is hard bc whites can pick and choose aspects of other cultures they like (hair, clothes, etc) without the backlash, although not only whites do that. If Perrie had been at an event for a Chinese friend, that would've been different, but here (and most in cases) it seems to be for the aesthetic.
oh i didnt know about that tradition. over here cheongsams are considered a piece of “traditional clothing” that’s considered formal wear (same with the samfoo, saree, punjabi suit, baju kurung, jubah etc). so people will usually wear it for celebrations, events and some people even wear it to work (i know my aunt used to do that) and i know some chinese brides do wear the cheongsam for their wedding or at least the reception but i didnt know that some chinese families have that tradition. but i totally get it why its annoying to see someone who doesnt know a thing abt your culture, the history and what it means to your people take a piece of it just for the aesthetics or as a costume and they get praises for it. especially if their people have been known to make fun of or oppress the culture itself when its the POCs doing/wearing it
