Kelly, Barbie's little sister, has had several re-designs in the past few years. The original Kelly was proportionate to Barbie
in size and design. Then, some of the Kelly dolls produced were given giant heads and skinny bodies (lollipop/anime style). At Toy Fair 2006, Kelly still has her larger head, but her body has been re-designed to be chunkier and more in proportion with her head. Overall, she is a nicer doll now (and will fit in little hands better), but I'm not sure she is in proportion to Barbie, so collectors may still prefer the first style Kelly for doing small scenes, photography, and display with their Barbie dolls.
