For a start, Christina Hendricks does not, as Featherstone claims, have any more of a realistic or attainable figure than Kate Moss/Victoria Beckham/latest popular target of skinny bashing. Yes she's a size 14. That's the average in this country. That's where any similarities with the average woman in this country ends. Hendricks might be a size 14, but there is not an ounce of fat on her. She's a size 14 because she's one of the few people out there who is genuinely "curvy" - she's got a generous chest and wide hips, coupled with a trim waist and long, lean limbs. In other words, she has an hourglass figure. Something around 8% of the female population is born with, and that cannot be achieved through any amount of diet, exercise or even surgery. Yeah, REAL attainable.
Secondly, as I've argued before, and hence will not give over too much attention to now, replacing one ideal of female physical perfection with another does not help. I couldn't be a size 14 if I ate nothing but lard for a month (and even if I could, I still wouldn't look like Christina Hendricks because I've got narrow hips and a small ribcage). All that achieves is shifting the pressure to conform from one group of women to another.
But thirdly, and more importantly, if we're going to start talking about role models, and what what women had ought to be "aspiring" to, could we leave the physical appearance out of it? Might we try aspiring towards academic and professional success? I know it's "out there" as an idea, but maybe Diane Abbott or even Featherstone herself are better role models than Hendricks, or that other cultural zeitgeist, Kelly Brook? Just a thought.
