How about someone that is not the correct skin colour or gender? Sure is awesome to have a ton of blue skinned, 9 foot tall humans walking around to dress up as Na’vi for us, no?
I want you to think about drawn proportions. No, really, stop and think of it. No one will ever be built like any of them in real life, for that is not pleasing to look at on paper. Take Ms. Marvel for example, at 5’11” and like 124 pounds. She would not look like that, bodies do not work that way. She would be a walking stick, not a muscular curvy woman. Stop and think about how many awesome female character out there aren’t from cookie cutter white-skinned curvacious body type, not too many, right? Not being that shouldn’t stop some one from dressing up as some one they love.
This shitty attitude towards anyone is part of the problem with the costuming world, there is no rule saying that you can not dress up like something because your body is not photo shopped all to hell and back like the ladies in Sports Illustrated or you are a exaggerated drawn image. Just because you do not look like that does not make the costume “inaccurate”, that just makes the person saying that an asshole for doing so.
Accuracy is all that matters to SOME people, but some other people just want to dress up for fun. To me? Accuracy matters, that is why I spend hours slaving over costumes to make sure that every god damn detail that I can do myself is there. There is more to accuracy then just someone’s body size/shape. There are the little details, the best fabric choices, the perfect shoes, the styled wig, the well-constructed prop, etc. Should I just go and burn my Captain America costume now because I am not male, nor built like Chris Evans was for the movie? Should every guy making the same costume that is also not built like he was do the same? I mean if “ACCURACY is all that matters” when it just comes to bodies, then not too many people qualify to be dressing up. Some us chose to make our bodies look right, some of us choose the rest of the costume, one is not really “better” for accuracy’s sake.
Simply put, just Don’t Be A Dick.
Shame on you for trying to shame people out of cosplaying whatever they like. Policing what people should or should not do with their bodies is deplorable.
