The Growing Up Skipper doll grew when you rotated her arm. Both in height and…cup size. Released in 1975, she was a doll about hitting puberty. Mattel conveniently left out acne, mood swings, braces, and getting your period in homeroom, though. While this does seem a little creepy and weird, when we put it next to any of the current Bratz dolls…maybe not so much.
