This is mine. They don't come in different body types sadly but otherwise I think it's fairly accurate for what I might wear if I were a completely fictional character in the GoT universe, though I think I would have lots of hidden weapons in that skirt because that is a dark universe (you can see I have a book though, because knowledge is power in any universe!). While the face and body tools are limited, the hair and costumes tools are pretty elaborate and versatile. As far as doll dressing goes, I had a fashion wheel in the 80's and that's been it until this (apart from a decade long on-off affair with the Sims - their clothes were less important to me than their houses), but I do love costumes and vintage clothing so thought I give this a whirl.
If you like Game of Thrones style costumes you should check out Michele Carragher's website. She is a hand embroiderer and illustrator who has also worked on many other period pieces.
Another GoT costumer - also named Michele! - is Michele Clapton, her website is here.
