I know that the majority of the Mattel dolls are slimmer then the older dolls. I haven't really decided which I would prefer. We have noticed some of the newer outfits fit the older dolls a little more snug then the AGoT's we have.

As always if there is a problem with the outfit I would change it out. Heck I ahve done so on many occasions. Out Samantha doll, which was a first year release, doesn't fit into her winter party dress very well. It is snug around her hips. But we have it and set other dolls into the dress. But if you aren't happy, change it out.

Good luck!
