In case you don’t know who Skipper is, she’s actually Barbie’s younger sister. And this Growing Up Skipper doll is very special for a number of reasons! With a tagline that says “She’s 2 dolls in 1 for twice as much fun!” and “Make her grow from a young girl to a teenager in seconds!” has most people going huh? Apparently, this 1975 Skipper has the ability to grow her boobs with a little bit of arm rotation. Not only is this incredibly unnatural to learn about puberty but it might give young girls a very wrong impression and a ton of disappointment when they realize that their boobs don’t grow when they rotate their own arms.
