Like every girl who has ever played with the most popular toy in history, I yank her clothes off and try to put on a new dress. Her creation has been kept so secret that the designers code-named the endeavor Project Dawn so that even their spouses wouldn’t be tipped off to her existence. I’m sitting in a bright pink room at Mattel’s headquarters in El Segundo, Calif., playing with a Barbie that only 20 people in the world know exists.
