No you don't.
That's not meant at all to be snarky or insulting. Barbie's just an alien.

Actually by that, my waist and hips are barbie sized. I have a 26 inch waist and 30 inch hips and i am 6'3"Put me in a corset and my waist gets right down to 24inches.
Why is that alien?
My daughters predicted height is 6'5" and if she is anything like me she will weigh around 65kilo's pre children. Why is that wrong?
