Deluxe Holy Nun Halloween Costume - Calgary, Alberta. Great to pair with a priest or wear to a theme party or Halloween. Not only is this Nun costume easy to wear, but it would be appropriate for work too. Super funny when the nun costume is worn by a man but great for any adult. Also a good choice for taking the kids Halloween trick-or-treating in Canada, no problem putting on the layers. Halloween doesn't get much easier than wearing this Nun costume.
