Usually, they're dressed to the nines in expensive clobber from the likes of Balmain, Givenchy and Balenciaga.
But when they're not wearing those pricey designers, they may be inclined to wear garms they've had a hand in creating.
These star performers have all decided to put their name to their own fashion labels.
Some of them have made the catwalk, and could already be in your wardrobe.
But what's your favourite?

The former Everton midfield star's line had a prestigious launch in New York with a catwalk show in 2016.
Cahill's line appeared at NYFW, where it received much fanfare and when it was sold online it flew off the shelves.
