We have gorgeous costumes for these ghosts that we built in our shop.
Past is for a woman. It's a white, sort of ice princess dress with a long train.
Present is a classic look for the role. Dark, rich green velvet with white fur trim. It's built long to accommodate the tall platform shoes we had the actor wear to make him appear about seven feet tall.
Future is wonderful and very creepy. We built a 12 foot tall ghost on a frame attached to a backpack, with rods to work the arms. it's light weight and the robes are beautifully tailored. Can give you instructions on how to operate him, but it's a very tall and elegant classic Ghost of the Future.
We have other specific props for the show as well, if you're interested.
