Actually the famous white swimsuit photo has a different story though it doesn't discount what you're saying.  She was pregnant.  This is easily confirmed on Google (kinda surprising people still try to pass it off as what she normally looked like).  She was technically a 10-12 dress size but this number means nothing since A) Dress sizes have radically changed and B) Most of her outfits were tailored to fit since she was an extreme hourglass figure.  She was by no means fat or even plump.  Here's her official measurements: Studio:  37-23-36 Dressmaker:  35-22-35 Weight:  118
