Some people believe Barbie gives girls a wrong idea of what they will look like when they grow up. They think the introduction of the doll was wrong because it made young girls believe they had to become skinny in order to be just like Barbie. As in earlier dolls, her head is disproportionately large. Unlike those, her breasts are large and her waist and feet are disproportionately small;. If her doll size proportions were converted into life size body measurements (breast size, waist size, hip size) only 1 in 100,000 women would match them, at least without plastic surgery. Someone shaped like Barbie would suffer back problems due to her breast size. She would be unable to support her weight on her tiny feet and could not walk.
