Ren faires are just an anacronism stew. Maybe some take historical accuracy seriously, but I’ve been to quite a few and have yet to see one that does. My local one has everything from ancient greece to steampunk Victorians. There’s even a Wok themed after Imperial China where these guys would fit right in. You see more fantasy then historical costumes usually anyway.

It’s just a place for nerds and weirdos to vibe, buy trinkets, drink, eat fair food, and wear cool costumes.
