nah, it just depends on what you’re appropriating from what culture… doing the stereotypical mexican garb is ok with mexico… so that’s cool, dressing in some religious outfit is incredibly offensive… like a native american headdress with a bunch of feathers… it’s also especially offensive in america because of the native american genocide americans great great grandparents probably participated in….

it’s all context… also in how you wear it… (are you making fun of mexicans or having fun with mexicans?) but mexicans are generally cool with americans wearing sombreros… and have a long tradition of american tourists doing so…. plus a sobrero and a mexican blanket is functional gear, not some sacred thing.
cowboys and their whole style is also entirely mexican originally, our cultures are quite intertwined.
that doesn’t change anything else and it’s just cherry picking examples.
