well it's obviously stolen, the real katykatcupcake has no steem account (she was asked and denied that this here is her) and she also writes in better english aaaand no cosplayer wouldd create an account to show cosplay photos without using the name known on other social media platforms.
Ok one last point because it's funny, she would never post a vampirella cosplay and writing that she wears a red dress because the color is nice ... she would write that she is cosplaying vampirella xD
