I’m not particularly keen on Mattel’s Kellys and Tommys, but this site, showcasing the work of doll customizer Loanne Ostiie, showing reroots, repaints and makeover on the little tykes, demonstrates to me that they can look cute, engaging and non-idiotic. The hairstyling is particularly impressive. Thanks, Kinjou!
P.S. Check out her gallery of custom Tommys, available from the index [first link].
