Virtually all of those post-shop would likely be classified as an overweight BMI. When two thirds of the population is overweight or obese and far less than 5% suffer from an eating disorder, I really find it difficult to jump on the "skinny advertising bad" bandwagon.

Has anyone ever actually demonstrated that media portrayal has an impact on eating disorders? I've seen some studies that show their rates don't change much over time, while obesity continues to skyrocket.

This kind of thin shaming seems like you're trying to snuff out a problem by throwing gas on an already bigger fire. We need to emphasize healthy body images. In the case of fictional, digitally created, idealized characters, I think erring on the skinny side does far less harm.
