The form of Barbie is physically unachievable. Some girls do try to achieve this impossible form. Since Barbie is so disproportionate as I stated earlier would not be able to walk. If you've seen a Barbie doll you know that the heels of Barbie are purposely slanted so Barbies plastic high heels fit. Barbie has been made to look athletic but has never truly succeeded in retaining the form of an athlete. There've been dolls called surfer Barbie swimmer Barbie and other athletic sport theme to Barbie dolls. Barbies thin waist and a large bust make it so you could not achieve her form without serious plastic surgery.
