Net-A-Porter Magazine

CosmoGirl was an American magazine based in New York City, published from 1999 until 2008. The teenage spin-off of Cosmopolitan magazine, it targeted teenage girls and features fashion and celebrities. It was published ten times a year and reached approximately eight million readers before folding. The last issue was December 2008. Subscribers instead received issues of fellow Hearst publication, Seventeen.

The magazine was founded by Atoosa Rubenstein, who was asked to create a mock issue. She repeatedly scrawled the word "Girl!" in bed using fuchsia lip gloss for use on the magazine cover. When she and her husband woke up, they were covered in lip gloss.

Ann Shoket was the executive editor before leaving the magazine to replace Atoosa Rubenstein as the editor-in-chief of fellow Hearst magazine, Seventeen. The last editor-in-chief was Susan Schulz, who was reassigned to special projects at Hearst Magazines.
