She turns 50 on Monday, but Barbie has a remarkable figure for a woman of any age. So what if you scaled her up to human proportions?
For a woman celebrating her half-century Barbie is remarkably unchanged from the young, fresh-faced Wisconsin girl who first came into the world on 9 March, 1959. And that's the problem.
Barbie Millicent Roberts is a woman with a very controversial reputation and mostly it stems from her long legs, tiny waist, ample bosom, slender neck and flowing blonde locks.
Some argue her body shape would be unobtainable and unsustainable if scaled up to life-size. They claim she would not be able to stand up because her body frame would be so unbalanced. A real life Barbie would simply fall over.

Can this be true? Her maker, Mattel, says it has never scaled her vital statistics to real-life dimensions. Of those who have - usually critics or academics - no one has come up with a definitive answer as to exactly what her measurements would be.
Serious research on the subject has drawn certain conclusions. Academics from the University of South Australia suggest the likelihood of a woman having Barbie's body shape is one in 100,000. So not impossible, but extremely rare. Researchers at Finland's University Central Hospital in Helsinki say if Barbie were life size she would lack the 17 to 22% body fat required for a woman to menstruate. So again, not an unachievable figure, but certainly not a healthy one.
