This is 100% ridiculous. The costume is frigging amazing. People making this argument clearly don't understand what "blackface" really is and how it was used back in the cartoons and live shows of the early 20th century. Blackface was a deliberate caricature with exaggerated eyes and lips and is absolutely offensive. This is a case of someone making a costume to honor a character and doing whatever is necessary to achieve the look. Since the face is half covered and there's nothing but accurate-ass cosplay for the parts that aren't covered, there is no way in hell this falls in the same vein as blackface in intent or execution. If she tried to do something like cosplay Barrett or Balrog/M. Bison, for example, it would be pretty impossible to not offend someone without resorting to some cinema level full face latex mask work - any amount of make-up would definitely come across as blackface for a character like that. The characters themselves already toe the sterotype line and having a white person try to pull them off would be tough if not impossible. This character technically isn't even a black guy, so.... yeah. She should be allowed to compete.
