Stephen Jones has made hats for Madonna, Kylie Minogue, Johnny Depp, Kate Moss and Erin O’Connor, and his modernist creations frequently sell for thousands of pounds. But his latest hat is a little different – it is designed to be worn by a horse.

Jones is Ascot’s official milliner this year, and he has spent more than 30 hours producing the world’s first equine hat to celebrate Ascot’s 300th anniversary.

On trend: Ambers the horse wears an orange and purple feathered hat designed by Stephen Jones to celebrate Ascot’s 300th anniversary, pictured with racegoer Elizabeth Beswick. The £8,000 feathered design will be worn by a horse called Ambers at Ladies’ Day tomorrow. It draws its inspiration from the timeless Ladies’ Day headpiece Audrey Hepburn wore in My Fair Lady.
