For anyone who wore a Juicy Couture track suit in homeroom or regularly watched The Simple Life, here’s a fact that will make you feel ancient: It’s been a decade since Paris Hilton launched her first fragrance, Paris Hilton for Women. Since then she’s created 16 more fragrances and racked in $2 billion in sales worldwide. Yes, you read that correctly: two billion. Last week, Hilton celebrated her 10th anniversary by launching her 18th scent, Paris Hilton Limited Anniversary Edition for Women, a more concentrated version of the original, housed in one very blinged-out bottle. She stopped by the Allure offices to show it off and chat about all things beauty.
