This makes the "glamour" mags and actresses appeareances irrelevant to the real woman as it isn't really a true gauge of society's concept of attractiveness but rather a concept behind looking good on screen which isn't the same.

An additional  problem is what magazine you're looking at.  Is it geared to men or women?

It's the fashion model/Playboy model difference.  Women in magazines and commercials and such aimed at men are, on average, bigger (in terms of measurement) and thus curvier than models in fashion magazines and runways.
