I live in Europe and I dont see anything offensive here, because it's just a cosplay and she wanted to look as closely to the character as possible, but judging by your comments Tropic Thunder should be one of the most offensive movies out there and Robert Downey Jr. career should have ended with this movie. I know it isn't the best comparison, but come one, it's sitting with a score of 7 on IMDb and I never heard that this movie is racist. Would it be ok if I cosplayed Robert Downey Jr from Tropic Thunder? Even to this day people constantly use "survive" gif which should be super racist but somehow isn't? I don't know, this racism thing is confusing.
