London Fashion Week is underway amidst fierce debate surrounding size zero models.Dublin-born designer Paul Costelloe kicked off the show with a new autumn/winter womenswear range taking its inspiration from Paris in the late 1960s.After the opening show, the British Fashion Council chief executive Hilary Riva said: "The Irish designer's collection has been a positive start to the week."She said: "What I think we saw there were great models. Very tall, and there wasn't one of them which I thought looked very young or excessively thin."And even Kate Moss's agent called for the industry to join the size zero debate saying its an issue that needs to be addressed.The industry has come under fire for not following the example set by Milan and Madrid in banning stick-thin girls from the catwalk.© Independent Television News Limited 2007.
