Rosalina doll dress is made by Leaf Nin. Here is her dA page: leaf-nin.deviantart.com/
Everything else, besides the dress and hair, I made with my own two hands. Like the rest of my dolls, Rosalina is made of lightweight paper clay. Her hair is rooted with Buttercreme nylon hair off Dolly Hair, and I made her crown and Luma.
Thank you Leaf Nin for making awesome doll clothes. Keep up the excellent work there!
