Anyway, in general:
Being obese is a problem; but so is the shaming and bulling that goes on. Representing a woman who is a size 6 as a "plus sized" model is frankly ridiculous. The average model is 5'11; at that height the recommended range is 135-156. The average weight of the models? 117.
(I'd also like to see women's jeans sold in waist/length measurement like men's jeans, rather than numbers - but that's an entirely different argument.)
While I don't want to advocate for bad habits, I don't think that means we as consumers can't push for diversity - in race, gender, and body-type.
