My husband and I registered for two of them just to see who would try to make us look like dark wizards. Both came from the same woman (two different occasions).
They're really just backwards robes. xD
Man...I wish I invented the Snuggie. It totally is just a backwards robe like @powderedplum mentioned and someone is making a fortune off of these ridiculous things!
I found a pattern for a crocheted one at Hobby Lobby today. I am kinda grossed out by these because of the laziness, but yet want one at the same time...
