I have a Picco Neemo D. She's small enough to share Kelly Doll clothes. From what I understand the body is the same except for the hands, forearms, calves, and feet between them and the other 14cm Piccos. I have heard of someone putting the Disney Mini Princess dolls on one with no problems, a perfect fit.
