The original version of Classy Carla does not have internal wires to help her pose. A second version was produced with internal PVC-coated wires. The second version is approximately .5 inches shorter, and her face is wider with more horizontal eye alignment. There is an extra line of text on the reverse of the tush tag for the 2nd version that reads, "PVC COATED WIRE". The second version was also sold with a comb.
