When I say Sylvia had some Cinderella inspiration, I specifically mean her hair!  Originally, Cinderella had strawberry blonde hair, as was very fashionable with Hollywood actresses at the time.  Over the years she was retconned to be blonde, but I think her original colors were a little more unique.  I wanted to give Sylvia something to make her stand apart from the rest of her ultra-blond family as well!
