Kim Kardashian wore perhaps the most famous dress ever to hit the red carpet of the Met Gala. The reality star sported an outfit made famous by Marilyn Monroe. Monroe was wearing the iconic dress when she breathily sang “Happy Birthday” to then-President John F. Kennedy in 1962. The dress is owned by Ripley’s Believe It or Not, which granted Kim permission to wear it. She had to undertake a workout routine to fit into the garment.
