In response to my query about measurements, Angelsdoll provided the following pictures and legends:
Close enough. They've achieved very similar proportions to the Doll Chateau adult male head, if not the exact same size. The head circumference and neck circumference are what I specified, and the width across the eyes is just under that of a DC adult male head. I've done everything that I can to ensure that Jareth's head will be in proportion to his chosen body. I approved the measurements and told them to send him to manufacturing.
