Well now they've dressed a racehorse up in a tweed suit. And it's not any old suit – it's a Harris Tweed three-piece designed by a former Alexander McQueen apprentice.
Each year at the fancy festival, more than 320km of tweed is worn by spectators.
Emma Sandham-King worked with a team of tailors and seamstresses for four weeks to create the horse's suit with more than 18 metres of tweed shipped specially from the Isle of Harris.
Using 10 times as much fabric as the human equivalent, the suit was commissioned by William Hill in time for the opening of the festival on Tuesday 15 March.
Emma said: "Creating the world's first tweed suit for a horse has been one of the biggest challenges that I have faced in my career as a designer.
"Some models can be real divas, but veteran racing horse Morestead was calm and a pleasure to work with. Tweed is undergoing a massive revival and this year's Cheltenham Festival will see the most tweed worn since the 1960s."
Jockey Sir Anthony McCoy unveiled the garment this week. And since, Morestead has been described as the "Naomi Campbell" of the horse-world.
That horse is more stylish than most humans we know. Madness!
