My husband and I came up with the costume idea months before Halloween and had a party just so we could wear them. Most of the main pieces we owned or bought from Goodwill.  What made the costumes was my makeup, for which there are all kinds of YouTube tutorials, and all the accessories: neck tats, rosaries, etc. if you could see me before, you would be amazed! Everybody said our costumes were the best, most original–funny, yet scary at the same time.
