Since the first guess it went so fast, we decided to make another one. We tried to make it super hard ;)
EDIT: I'm feeling a little better so I can post. But that wasn't why I'm editing this.
The hint is: It is a retired doll and a retired outfit.
EDIT: Another hint! The retired doll is a JLY.
If nobody can guess it by Marcfh 6, then I am putting up the answer.
