Luckily, I have a visiting 3 year old to test out the set. The dress met with approval, not too scratchy, short enough not to trip over. She liked the large plastic locket. Earrings hurt, and the tiara was not worn.
She slept with the Sophia doll. My granddaughter said the set needed Sophia slippers.
She said she was familiar with the Sophia story, but I'm not sure she is. I know I'm not.
Sophia is a new Disney Princess, the subject of a TV series that's not watched at my granddaughter's house.
