In 1975 Growing Up Skipper was released. The gimmick of the doll, which led to much controversy in the newspapers, was that if Skipper's arm was rotated, the doll would become an inch taller and small breasts would appear on her rubber torso. In 1979 Skipper's entire appearance changed. She was advertised as 'Super Teen Skipper.' She had a new body mold which included small permanent breasts, and a different head mold that made her look slightly older. In 1985, Hot Stuff Skipper was released, which had another new head mold that included the addition of dimples and a longer face.
Skipper changed again in 1988 with the release of Teen Fun Skipper. Her new body mold was taller and more graceful. Her waist was more flexible and her breasts were slightly bigger. Her eyes were also enlarged, giving her a cartoon-like look. At this stage she appeared to be somewhere between 12-15 years old. Later, Skipper had a new head mold with smaller eyes in a Pizza Party line, but with the same body mold. Many collectors believe that the 'Pizza Party' head mold was the most popular, if not the prettiest, version of Skipper. Dolls with the 'Pizza Party' Skipper head mold and the 1960's head mold are the most sought after Skipper dolls by collectors.
