But what if there was something more sinister behind fashion designers’ efforts to foist anorexic chic as the female archetype: Stop heteros (AKA “breeders”) from having children.

Yes, I'm sure the fashion industry is all one big homosexual conspiracy to keep heteros from breeding...< /sarcasm>

Seriously, I doubt 1% of fashion designers understand anything as complicated as the effects of nutrition on reproductive biology.

On a subconsciouse level they might feel that if they can't breed, why should we? I am not a Fruedian but this might be one motivation among many.
