That is an absolutely terrible way of thinking. Any cosplayer has every right to cosplay in anyway see fit, no matter the shape or size or if something might be different. Doesn’t matter if said costume or partial costume is lacking in “quality.” Every cosplay is completely awesome. There is no such thing as a reason to not cosplay. If you want to dress up and go have fun at a massive pop-culture event then do it. Doesnt matter if you throw a black towel over your head and poke holes for eyes and call yourself Batman. That is still a wonderful cosplay, and this guy in the picture above is awesome!
