Her friends Elle Macpherson, Cindy Crawford and Kate Moss have all done it.
And now it looks like the turn of fellow supermodel Claudia Schiffer to turn her hand to designing her own fashion collection.
"I have been approached so many times over the last 20 years but it has never been the right time," the German beauty recently told the Daily Telegraph.
"Now I would consider it but it would have to be the right thing. "They would need to be clothes that I would want to wear," explained the 39-year-old.
But for now fans of Claudia - who has said she has no plans to return to the catwalk - will just have to watch this space.
