But Ms Moss told BBC Breakfast she thinks the body positivity movement is "slightly under threat"."The wider industry is veering towards a very thin model look," she said.Adding: "With a rise of weight loss injection drugs there's a rise of talk in the media of people taking these drugs and I think that's really pushed this idea of everyone has to be thin much more to the fore again."

She said "bigger girls are simply not being cast" for fashion campaigns and raised concerns over a rise in eating disorders among young women along with more "thinspiration pictures" being posted on social media.Ms Moss says the use of body positive curve models has certainly declined in the high fashion industry over last few years but it is still unusual to see very thin models used in high street campaigns.
