If top editors make trends, then it’s time to get pregnant. At fall shows, the only thing Anna Wintour is holding tighter than fur coats is her shiny-haired daughter, Bee Shaffer. The Europeans are also in step, as French Vogue editor-in-chief Carine Roitfeld has been spotted all over town with her party-hopping daughter, Julia. And it’s not just daughters who are being shown off; Cathy Horyn of the New York Times has been toting her son, Jacob, around. This trend is sure to stick: Youth never goes out of style.
