Sister Act night

If you're like me and haven't bought your nun costume yet, a way to make it cheaper is to use a graduation gown (if you already have one lying around). Instead of buying the entire outfit, you can either make or buy a collar and headpiece. The collar and headpiece can be found for less than $10 on eBay. Or you could always go the "sexy nun" route, which apparently is more common than I thought. Seriously, type in "nun costume" on eBay and marvel at the selection of slutty nun costumes.
