You’re wrong. Today’s supermodel is more like Marilyn than ever before. True that there is more enhancement but the best today are not thin, just really shapely.
Muscle tone is what I would say is required of today’s supermodels. Women also have a layer of fat just below the skin that men don’t have, which helps to smooth out the features. Any extra fat is like a cancer to a supermodel. There is a fine balance which has to be maintained which involves workouts, diet, and natural good looks. Between starvation and fitness.
