Crawford recently admitted she wouldn't have become a successful supermodel if she had started out in 2009, because her body is too curvy for today's catwalks.
The 43 year old is convinced fashion magazines promote an unhealthy lifestyle to young girls and she's hoping consumers will make an effort to avoid these products in a bid to send a message to industry bosses.
She says, "We as the consumers, we as the women, have the power. If you don't like something, don't buy it. Don't buy the magazine if you don't like what it says. If you don't like the image a brand is putting out, don't buy it.
"What I really don't agree with is people who complain about it but still support it. You're giving your power away. If people don't want skinny models, stop buying the magazine with the skinny model, and believe me those magazines will change fast. It's business."
