I've heard people claim cultural appropriation over this or that, but I'm not convinced it's a real thing, and not just people being offended on behalf of someone else.
That's not to say that cultures don't get appropriated, but is that a bad thing? White people rocking dreadlocks, cool. Black people sporting a kimono, nice. Asian people with Klan robes, what.
We live in a culturally interconnected global community now, no group has ownership over aesthetics.
