This is not anything new, obviously: the idea that you need to be skinny in fashion.
I don't even need to get into it, really. From a teenage Ali Michael being sent home from Paris for gaining a few pounds to Carine Roitfeld famously hiring only thin girls at French Vogue, it's something that we've all talked about until we're blue in the face. The fashion industry has a very specific idea of what a woman's body should look like, and it's just unfortunate for everyone else that that body is only realistic for a tiny percentage of (generally unhealthy) women.
For a while, two talented, gorgeous, real women - Kate and Laura Mulleavy, the sisters behind Rodarte - seemed an anomaly, in that they were not only part of the fashion industry but revered in it - and were hardly sample sizes.
And then Vogue suggested that they go on a diet.
