Elle Macpherson ordered hopefuls to cover up on the catwalk during filming of her Next Top Model series.
The supermodel and underwear tycoon, who earned the nickname The Body for her stunning figure in numerous swimwear shoots, felt uncomfortable about the wannabes flashing too much flesh.
She acted after early auditions for Sky Living's Britain and Ireland's Next Top Model had involved the contestants appearing half naked.
Elle, host and executive producer on the reality show, thought it was unfair that the girls were being asked to appear in next to nothing.
Viewers will see contestants at the Glasgow audition parade in front of judges in skimpy bikinis and underwear, while those in London strut their stuff in their own clothes.
Elle, whose underwear company Elle Macpherson Intimates celebrates its 25th anniversary next year, revealed she put a stop to the tiny costumes.
Speaking at the launch of the seventh series, she said: "We started off putting girls in bathing suits and when I saw the first lot come in I just was like, 'I can't do this to them, it's not fair'.
"I'm really interested in the whole, the personality of the girl, and often that's projecting in the way they dress and it just felt inappropriate.
"It's very uncomfortable for a girl to stand in front of people like this, naked, freezing cold, so we just said, 'No, it's not fair'."
She is joined on the judging panel by X Factor stylist Grace Woodward, designer Julien Macdonald and male model Charley Speed.
