Carrie has been scaring audiences for years. We have all seen the pictures of Carrie covered in pig’s blood the night of prom. This is an easy costume to recreate yourself. All you need is a long tank top dress, slip, or nightgown that has spaghetti straps and that you don’t care if it gets ruined. Simply buy a jug of fake blood (or make your own) and cover yourself with it from head to toe. Top off the look with a tiara or a bouquet of flowers. If you don’t feel like making your own, you can buy one at partycity.com.
