Sometimes it's good to go through the closet once in awhile:

Workers sorting through party rental costumes at a London fancy dress shop have discovered the original Obi Wan Kenobi robe worn by the actor Sir Alec Guinness in the film "Star Wars", the shop said on Tuesday.

The robe was stored for years in a warehouse by film costume company Angels and Bermans before ending up with a batch of old monks' outfits in the company's high street party rental shop, manager Emma Angel said.

I wonder if Olivia's big enough to be a Jawa for Halloween?
