In Mathematical terms, the study of Barbieism is the study of Topology. If you had a completely malleable doughnut, you could twist, shrink, enlarge, distort it's dimensions to infinite extremes and it would still be a doughnut. It would still have it's doughnut essence. As long as it is not ripped or torn . Then it becomes a croissant.
Croissants are French.
In Barbie terms, Topology is the distortion of the female form. We have even applied for government grants to continue these highly scientific inquiries. But we have, as of yet, always been shunned. We are relegated to case studies in seedy bars and street corners. With only a few million dollars of seed money, your humble essayist could finally discover the primordial essence of femaleness.
