Hi, it would be easier to identify with certainty the doll you have if you included a picture. However, from your description it sounds like your doll might be a "Rosemary" supermarket premium doll from the '50s. I have one here, but she doesn't have original clothing. The body is rubber, the head is vinyl. She has high heel feet. Her hair is rooted, a shade of auburn, in a short, curly bouffant. Probably earrings; maybe a necklace. The dress is blue chiffon in tiered layers...does that sound like your doll? If not, put up a picture here for us. I don't think she was specifically intended to represent Cinderella...I'd never thought about it.
