This is a rare doll from the early-mid '90s made by Giochi Preziosi. She is wearing an outfit from a Bandai Sailor Mars doll, which fits pretty well, though her shoes like to fall off.
Unfortunately, while taking these pictures, both of her legs fell off. I don't know if they can be reattached as I haven't tried.
Both legs have glitter all over them from the previous owner.
Tiara is broken.
Still a beautiful doll! Face has some light purple marks near her eyes.
