Chanel designer KARL LAGERFIELD has weighed in on the size zero debate, insisting the idea of regulating models' weight is "revolting".

Lagerfield, 68, refuses to clamp down on super-skinny models on his catwalk, and is disgusted the fashion world is even considering a ban, because he doesn't see what all the fuss is about.

He says, "The idea of regulation is revolting, but so much of the moment. Models are about looks, not about weight.

"It's part of this new, PC fascism."
