This debut contains one basic doll, three dressed dolls and three fashion packs. I would definitely purchase these for a child that was ready to move on from, for example, the American Girl dolls although they certainly could exist side by side in a child's collection.
Here they are.
The dolls look to be fully articulated although I could not find information on their material and construction.
Looking back in my blog, I found a picture from last February's Toy Fair of the City Girls. Apparently two of the three dolls shown there did not make it into the debut. Perhaps they will appear towards the end of the year.
