BWITGG, I don't think you're nutty for suspecting a fashion conspiracy to keep women starved and hungry! It happens to be a pet topic of mine, and loads of fashion/beauty editors agree with you; even some of the big British model agents do.
Unfortunately, whenever I mention it somebody posts a link to a 'documentary' of fashion adverts that seem to celebrate mutilation and death. The project was an entry for a fashion photography competition, made by students - the competition's theme was "Death". There are plenty of scary examples around for real, we don't need to repackage an art project as a documentary.

I simply couldn't bear it if anyone thought I was tired or something!
