The Duchess of Cornwall joined racegoers at the Cheltenham festival today - and the colour of her hat cost bookies dear.
Camilla arrived at the sporting event looking stylish in a brown tweed skirt and coat by Roy Allen and a light brown, fur-trimmed hat by Lock.
Rupert Adams, from bookmaker William Hill, said they paid out to any punters who picked the colours white, cream, yellow or brown for Camilla's hat and said half of all bets won.
The Duchess's arrival at the famous racecourse was delayed by 20 minutes due to foggy conditions and her helicopter had to be diverted to a nearby airfield.
She was then driven to the course where she walked through the crowds and across the parade ring to the Royal Box.
Camilla's son, Tom Parker Bowles, joined her for a day watching some of the country's best National Hunt jockeys.
The Duchess, a keen horse enthusiast, was invited to the races by the chairman of Cheltenham racecourse, Robert Waley-Cohen, and later will present a trophy to the winner of the BetVictor Queen Mother Champion Chase.
Camilla was "delighted" to win what is thought to be a private bet between her and son Tom Parker Bowles.
The writer handed over money to his mother on a balcony after they watched Faugheen, ridden by Ruby Walsh, storm to victory in the first race of Ladies' Day.
A spokeswoman for the Duchess confirmed: "The Duchess of Cornwall is delighted with her win.
"She is a great horse lover. All her family love racing and she always enjoys coming to Cheltenham."
Camilla later entered the winner's enclosure to present the trophy for the BetVictor Queen Mother Champion Chase, which was won by Sire De Grugy, ridden by Jamie Moore.
A large scarf with the horse's name on it was placed around her neck before the ceremony.
Camilla first presented trainer Gary Moore with the trophy, before giving an award to jockey Jamie Moore.
She is expected to leave the racecourse shortly, and will travel by helicopter back to London.
