Notes on fashion and sizes

One of the unfortunate side effects of the craze for uber-thin models is that the counterparts tapped to model plus sizes generally register more "average" than "plus sized." Given the proliferation of euphemisms like "A. Smith Woman" employed to denote plus sized lines, it can be surprisingly difficult if the designer is trying to showcase women with "normal" bodies a la the Dove campaign or actually marketing specialized sizes. See, e.g., this woman, who looks fairly normal/seems barely smaller than the woman in the plus size advertisement. I therefore can't tell if the dress being sold is supposed to follow normal sizing, be a maternity line, or the like.
