First of all..........DAMN!!!!!!!!!!!!!!! That scared the coffee out of me. Great prop. I wonder how many thousand dollars it is. Secondly, If you just need something similar I would make my own. Go to local thrift stores and look for old dresses and skirts. I have found some really great ones around here. Use several of them. Cut them up and piece them together to come up with the look you want. Add some old cheese cloth type fabric around the arms and wrists. Sashes or belts made from old scraps of fabric. If you can't sew do what I do when i am in a hurry...hot glue it together. LOL. I am sorry I cannot actually tell you where to find a costume like this already made. Good luck with it.
