Kourtney Kardashian delivered “90s vibes only” in spunky throwback photos that she posted to Instagram on April 9. The Keeping Up with the Kardashians star, who is a week away from her 42nd birthday, shared photos that were taken when she was about 20 years old. The ’90s version of the Poosh blogger flashed a dramatic pose as she posed in lacy black lingerie for photos that were snapped in “1999 to be exact,” which Kourtney clarified in the caption.
