Rare Antique Miniature Couture Mannequin Fashion Fine Porcelain Doll vintage HTF

I am unsure of the age of this very beautiful little porcelain doll. She has both of her jointed arms, there is a remnant of a wood peg that would’ve held one of them in place. You can see this in photos. Her fingernails are painted and her facial features are painted on. Instead of separate legs, she has this really lovely skirt piece and can stand securely. I believe that this is a vintage, sewing doll, you would’ve made miniature clothes for it, but I’m not 100% sure. There are no makers mark on it. I would actually love any information anyone knows about this piece as I have been able to find nothing about this style online. ( And I have a duplicate in my own collection.) No cracks or chips noted. Again she is stunning! Please see photos for details and condition.
