I'm looking to be Judy Jetson for halloween?

and I would like to create my own costume and not purchase the cheap one they sell at halloween stores. However, I'm having trouble finding some Judy-like futuristic tops/dresses and skirts. I was thinking of a vinyl outfit, but every time I search for it, I get less than good results. If anyone has any ideas about clothing or accessories, or whatever, I would appreciate it!
