Skinny women are oversaturated in advertising.
However the Dove ad isn't indicative of real life either.
Popularity will always be "demonized". Part of a weird build you up, to break you down syndrome society has.
It's all just pandering to maximize their revenues by giving the illusion of being inclusive and/or diverse.
Part of me wanted/still wants to be in advertising, but the lengths that companies go to reach out to customers sometimes is a bit excessive.
