I think it's not flaunting, as much as he means for them to be COMFORTABLE with their own body, in their own skin.
The fashion gods have already dictated that fat people are to be shunned, gawked at with horror, pitied, and it translates in the fashions available for plus size people, for women, the traditional loose shirt and the moomoo are all they have!
I think Carson is doing all of us a favor by showcasing women in ALL sizes, and telling them it's alright for them to want to wear the fashions made for waifs.
Important point: Those people on the cover of Elle/Vogue?
They aren't real! True that they are genetically blessed (beautiful features, slim body) but even that isn't enough to make the cover; they have ERASED every single flaw by touchup and computer manipulation! No botchy skin, or dark spots, nada! No wonder some people kill themselves over depression in body image, what these magazines are showing are not even REALITY!
