Elle Macpherson says certain body types are more successful in fashion because they work better with clothes.
The Australian supermodel has discussed what it takes to excel in the industry and admits tall, slim women are more likely to make it to the top.
However, she wants people to know fashion isn't as inaccessible as many think.
"There are many professions that have a body type that works best for them; for example if you're a jockey there is no point being 6ft 3in (1.9m) and trying to ride a fast race horse; it doesn't really work," she told UK TV show This Morning.
"I don't think that there's a discrimination against tall jockeys it's just that is not the best body type for that particular job.
"In fashion there is a body type that works better with clothes; clothes hang better and look better on a certain body type.
"Having said that I'm six foot. I'm not super skinny - there have been many girls who are fit and strong and have been very successful. Or there are girls like Kate Moss who are very slender, she's tiny. So the fashion industry really is growing, there are lots of different types of beauty."
Macpherson appears on Britain & Ireland's Next Top Model and has explained what she looks for when trying to find the fashion face of the future.
While beauty is important, there is another element Macpherson requires: "There's the typical things - tall, broad shoulders, long legs, [but] for me there's got to be something that when she walks into the room [that means] I want to know more about her. Who is that girl? She has an aura about her, there's something going on inside her that interests me."
