I have a question: Remember the picture where the indian guy with the turban dressed up as captain america? And remember that post scolding disney for selling native american lone ranger constumes? Well, I belive that you can cosplay any character regardless of race (So its totally ok for like a black person to cosplay as Jimmy Neutron) but IS IT WRONG if, say, a white girl wanted to dress in native american clothes to cosplay pocahontas?
I can't tell you if it's "okay" or not or "wrong" or not to cosplay as Pocahontas or any other character because this tumblr blog is not intended to be anybody's personal permission-granting "____ friend" Â (As in, "but my friend is ___ and she gave me the okay!")
There's some more information on this under the cosplay tag, but to be brief: Â There is no objective answer as to whether or not it's wrong for a white person to cosplay a person of color--it always depends on context and who you are asking. Â Â
That being said, many people find white people dressing up in (what is purportedly) "Native American clothes" to be offensive and a form of cultural appropriation, and many people think Pocahontas is a deeply racist and problematic movie.  You can of course continue to believe your beliefs, but please don't act surprised if anyone challenges them.
