Hey, can I wear a Native American headdress?

So I follow this hippie community on Pinterest. It’s mostly relatively inoffensive pictures of skinny white women with long hair wearing clothes I might like. But every few days, we get a photo of a skinny white woman with long hair wearing a Native American headdress. These always get like 872 repins and likes, and I’m always all WTF?

I’m attempting to see the best in people rather than the worst, so I assume this is happening out of ignorance rather than an active desire to be offensive. So I thought I’d make a handy flowchart that will let you know whether it’s okay for you to don a headdress as you go forth to your music festival or whatever other hippie shit you’re doing this weekend.

Hope this helps!
