She's a Winter Season Kurhn that Kristen rerooted for me with Dollyhair Nylon in After Midnight. Since nylon hair is such a pain to work with, I really hated to ask her to do it...but I think the doll turned out beautifully.
The Seasons dolls have a different face from the typical Kurhn; a bit older and very serene. Aside from her brown eyes and long hair, I think that Sophie looks like Kitty Kitten from Space Runaway Ideon. Hold onto that head, Sophie! XD
