Beauty attacks 'size zero' models.
Eleanor Glynn called on the fashion industry to show a greater variety of shapes and sizes.
The 5ft 9in 20-year-old was rejected by several top modelling agencies despite being a size eight to 10.
In a speech at the Oxford University Union, she said the fashion industry had a responsibility towards young girls who idolised models.
Speaking beforehand, she said: "They seem to have been going for the gaunt, almost cocaine look for the past few years and I think it is time we have some variation."
Miss Glynn said she was rejected by three London modelling agencies who told her she was the wrong shape.
"It affected me at one point until I won Miss England but the girls who don't have other doors opening can fall on eating disorders," she said.
"It is not an achievable look. I would like to see girls like, for example, Kate Winslet and Liz Hurley.
"I'm not saying they should ban all super-slim models but I do think it would be good to have more variation of size.
"We are almost being brain-washed at the moment into believing this is reality."
Miss Glynn, who is from Sanford on Thames, Oxford, was crowned Miss England last July.
Her comments follow the second day of catwalk shows at London Fashion Week.
The build-up to the event was overshadowed by the British Fashion Council's decision not to ban "size zero" models from the catwalk.
