Any ideas for Halloween fancy dress for my kitty? ?

Im having a Halloween party for me and my friends and i wanna dress my kitty up he's light ginger and white and is really relaxed and docile so i don't think he will mind. The theme is super heroes but it doesn't really matter what he wears, something easy to wear that won't annoy him but looks really good. E.g. A bat, superman that sorta thing any ideas?
