She was curvy in the right places, but I wouldn't call her a bigger girl by any stretch.

"Marilyn’s dresses were often sewed onto her and, as Lena Pepitone asserts, her clothes were often so tight that they required regular mending of split seams and zippers. To get her clothing onto a dressform without ripping out seams and re-sewing them, they would have to choose smaller-than-Marilyn dressforms so that the dresses would maintain a normal amount of ‘ease’…though in Marilyn’s lifetime, she wore them without that ease. If you stuffed them as tight as sausage-casings, as she wore them, you could have an accurate 3-D depiction of her nude body size/shape (since it is reported that she didn’t even wear underwear [Lena Pepitone], let alone girdles and other shaping garments popular at the time.)"
Her measurements: 35-22-35 (Dressmaker’s Claim), and height: 5 feet 5 1/2 inches.
You show me a "curvy" girl with a 22" waist these days. Curvy now seems to mean 30" waist and up.
