Marilyn was 5'5, 118 pounds, and had a 22 inch waist. That's not plus sized by any stretch of the imagination. In fact, when the famous white dress from The Seven Year Itch was being sold at auction, it was placed on a size 2 mannequin....and couldn't be zipped up. A collector of her clothing has had to modify child size mannequins to display them. She was tiny but extraordinarily curvy, which is why she's still recognized as the ideal bombshell figure to this day.
