The French luxury giant owns several major fashion houses, including Gucci, Saint Laurent and Alexander McQueen.

Models under 18 will no longer be used in their fashion shows and photo shoots.

The policy will come into effect for the 2020-2021 Autumn/Winter collections.

Francois-Henry Pinault, the Chairman and CEO of Kering has said that ‘we believe we have a responsibility to put forward the best possible practices in the Luxury sector and we hope to create a movement that will encourage others to follow’.

The Chief Sustainability Officer of Kering added ‘in our view, the physiological and psychological maturity of models aged over 18 seems more appropriate to the rhythm and demands that are involved in this profession. We are also aware of the role-model element that images produced by our Houses can represent for certain groups of people,”.

In 2017, Kering adopted a charter on working relations and well being of models.

They introduced a minimum age of 16 and committed to only working with models with a valid medical certificate certifying their good health.

Kerings decision comes as fashion brands are increasingly trying to be more ethical in their working practices.

In February 2018 Vogue publisher Conde Nast banned models under 18 in editorial shoots.

At the time, an editorial in Vogue said  “Vogue, along with a number of other publications, has played a role in making it routine for children – since that’s what they are – to be dressed and marketed as glamorous adults.”

It continued: ‘No more: it’s not right for us’.

Fashion designers, Christian Dior and Gucci has also pledged to drop super-skinny models for their catwalk shows.

What is wrong with hiring young models?

It has been the norm in the fashion industry to cast models who are under 18 and many supermodels start their career at a young age.

Naomi Campbell, now 48, was just shy of 16 when she launched her career. Kate Moss, 45, was discovered at the age of 14. Brooke Shields was just 14 when she appeared on the front cover of Vogue in February 1980.

Currently, 17-year-old Kaia Gerber is a rising star, while the late Karl Lagerfeld’s godson Hudson Kroenig, 11, was regularly seen on the catwalk.
