The worldwide problem of weak, starving, nutritionally deficient, anorexic models all starts with the designers. They draw sketches of outfits they'd like to make, using ultra-thin cartoon illustrations of women that are totally beyond any realistic proportions, and because designers envision these clothes on ultra-tall sticks, they think they only look right on ultra-tall sticks. They want to sell their merchandise, so, they make the sample size (the demo piece to be shown on runways and in photo sessions for retail buyers to examine) in size 0, 1 or 2. If a model wants to work, she has to fit into that sample size. So, she's under constant pressure to eat less than 500 calories, per day, and exercise for 2 to 4 hours, every day. All so she can look like a walking corpse on the runway.
It HAS to stop! Designers would sell a shit-ton more clothes if they designed and manufactured them in the sizes that women truly are in this world, and statistics show that the average North American woman is 5'5", 160 lbs. (size 14-16). Wake up, designers. YOU are the core of this very serious problem, and the change starts with YOU.
