A Nun Costume is a unique and funny way to add a splash of holy water to Halloween! These Catholicism-inspired outfits can be totally holy or even a little sinful with our Sexy Nun Costumes. Sizes range from child to adult. Not only for Halloween, nun costumes can be useful for school plays or any other event where a costume is required but you don't want to go for something typical. It's a choice that really stands out among a sea of witches, ghouls, and ghosts. No matter what your message this holiday season, a nun costume can get it a-cross!
