>> Dior and Saint Laurent on the catwalk for Paris fashion week. This year though it's not only a demonstration of their latest collections. They, alongside many other labels, say they're honoring a new charter to ween the fashion industry off it's association with unhealthy models. It's been set by parent companies Kering and LVMH, two of the world's biggest fashion houses.
Reuters' Sarah White in Paris says now there are official age and size limits for the people parading their clothes.>> Obviously, this isn't a new phenomenon. But there has been a sense that there are a rising number of cases of young girls suffering from depression. Young models have been through eating disorders, having panic attacks.
This also comes at a time when there have been a number of scandals in recent years that have come to public attention. Casting directors sending young girls home for being overweight.>> Campaigners are hopeful the new rules are a step in the right direction. Two years ago Dior made waves by having this 14-year-old girl walk the catwalk in Paris.
>> It's important that this industry takes responsibility that everyone in the industry does. I think it's that the houses must, the designers must, the casting directors must, the agents must, the models must. They need to look after themselves, they need to be responsible.>> The new charter won't use models under the age of 16, and has ruled out the United States infamous size zero.
>> I mean, this is by no means, something that's being implemented across the industry. But what is significant here is that Kering and LVMH are two of the world's biggest luxury goods companies, and their brands transcend borders. So they're the owners of brands like Italy's Gucci. Like Britain's Stella McCartney, like Mark Jacob's of the US,
>> That goes beyond what's happening at a local level, which could have more of an effect than initiatives taken by countries such as France and Israel, which banned underweight models several years ago.
