Can a white person wear cheongsam?

Can I ask a question about cultural appropriation? Specifically, is it appropriate for a white person to wear a cheongsam, a traditional Chinese garment? I understand that fashion is a form of self-expression and that people may want to wear clothes from different cultures, but I'm wondering if there's a line that shouldn't be crossed when it comes to cultural dress. Should individuals consider the cultural significance and history behind a garment before deciding to wear it? Or is it simply a matter of personal choice?
