This is inspired from a fic I read called A Dangerous Game, by tsukithewolf (on ao3) I can’t remember if the costume is one hundred percent accurate, but eh. It was fun to draw :)
I would also recommend the fic, though bear in mind it’s like over 400,000 words and also part 1 of 2... I really liked it though, (as a ‘I want to read about MISERY’ fic-)
