Fashion model Kelly Knox, 32, from Enfield, was born with one arm and after winning BBC Three reality TV show Britain’s Missing Top Model in 2008, now advocates diversity in the industry.
The 32-year-old said: “Back then you didn’t see models like me in the industry. Everyone deserves to be represented in fashion.”
Size 14 model Iskra Lawrence, 25, started modelling at 13 but found it increasingly difficult to fit into the designers’ sample sizes of six and eight.
“I really experienced a lot of body image issues,” she said.
“I struggled with my self-esteem and I can’t blame that on the fashion industry. But it put me under certain pressures to look a certain way.”
But she said she decided she “was not going to change” and now is a plus size model.
“I eat what I want but I make sure that I take in the nutritious foods and exercise. I want to look after my body because I only have one and it’s my home.”
Research carried out by Simply Be found over three quarters of people questioned think zero sized models should be banned from catwalks because they promote an unhealthy body image.
Eight out of ten people surveyed said that if designers used more representative models it would help them sell more clothes and 73 per cent urged high street retailers to use a variety of different sized models in their campaigns.
The statistics are supported by a study from Warwick Business School which found that using overly idealised female imagery at the forefront of an advertisement is more likely to provoke scorn than shopping.
Liz Wilmshurst from national charity Reach, which supports children with upper limb differences, said: “Kelly Knox is one of our ambassadors and is a great role model for Reach kids, so it’s brilliant to see her campaigning for more diversity on runways.
“Fashion is supposed to be about expressing your individuality, so why should all models fit one mould?”
The launch by Simply Be follows calls from one women’s group for London Mayor Sadiq Khan to end support for London Fashion Week because of the use of “undersized and unhealthy” models.
