On October 21, reality TV star, entrepreneur, and influencer Kim Kardashian celebrated her 44th birthday. Her older sister, Kourtney, shared her well wishes by posting some intriguing throwback photos on Instagram.

In one of these vintage snapshots, likely taken over 40 years ago, the future stars are still just young girls, posing in matching dresses with white collars and black bows.

In another photo, they appear to be around 6 or 7, likely caught just before heading off to school, holding their lunchboxes in hand.

Kim herself shared glimpses on her Instagram Stories, showing that she came home to a festive arrangement of black balloons, a plush figure made to look like her in a bikini, and lavish bouquets of white and pink roses.

Just recently, Kim made a splash at the annual Academy Museum Gala in Los Angeles. Ditching the traditional black-tie dress code, she stepped onto the red carpet in bold mini-shorts and a corset with a plunging neckline, showcasing a daring vintage look from French fashion house Mugler’s 1998 spring collection.
