A Royal Triumph. Beaming Queen congratulates Gold Cup winner Frankie Dettory, as she enjoys her third day at Royal Ascot with Ugini, Zara, and Autumn. The Queen was all smiles at Royal Ascot this afternoon as she congratulated Gold Cup winning Jockey Frankie Dettory after he romped to victory on Strativarius, his fourth triumph of the day. Her majesty broke with her Royal Blue tradition as she dawned a stunning dove grey coat and floral silk dress with accents of lemon yellow to ladies' day. The monarch, 93, arrived for the afternoon of racing in an open top carriage alongside her son Prince Andrew, Duke of York, 59, daughter Princess Anne, 69, and her husband vice Admiral Sir Tim Lawrence. Having worn traditional pale blue for the past two days of the meet, Queen Elizabeth the second opted for a departure from her usual bright color palette, and completed her look with a pleated hat with spike flowers and a striking floral brooch with complementing yellow diamonds, which was a present from the Sultan of Ammon. She coordinated perfectly with her daughter the Princess Royal, who looked elegant and a pale green ensemble with a subtle nod to her mother's yellow theme and her accessories. They were followed in the second carriage by Princess Eugenie, 29, who wore a beautiful forest green dress with a hat by Bundle McLaren featuring a striking twisting feather. The Royal was joined by Mr James Fellows, who founded the Bridge of Hope Charity Initiative, which helps people who have fallen off the career ladder get into horse racing, and the Viscount and Viscountis Brookborough. The third and final carriage carried a grin in Zara and Mike Tindle, with the Queen's grand daughter stunning and a teal dress by Claire Miss Sylvania and a complementing sculpted hat by London Milliner Julie at Botterall. They were joined by Peter and Autumn Phillips, who looked dazzling and a floral dress by Claire Miss Sylvania and an ivory cocktail hat by B Smith. With the clue in the name, Royal asked it is hugely popular with the monarchy and her majesty has attended every year since ascending the throne, and this year has been no exception. Having been forced to whip out a braille yesterday, the Queen will have been relieved that the heavy rain has cleared and been replaced with glorious sunshine.

Unsurprisingly, hats wear the focus of many racegoers outfits, with flowers, feathers and beating all on display. One woman went for a gravity-defying self-pouring teapot, which hung above a stream of flowers that poured into her hat. Even animals got in on the action, and a well-behaved dog was spotted sitting down with a tiny top hat on his head. Visitors to the Royal and Queen and enclosures have to abide by a strict dress code, which does not allow bare-mittered sore strapless dresses, but for guests and the Windsor and other enclosures the rules are more relaxed. While there is no official prize on offer for best dressed lady as there is at other race meetings, ticket holders were still eager to put their best foot forward. Up to 300,000 people are due to descend on the event over the course of five days and naturally the stylish day out is a magnet for celebrities, and is predicted to be a star-studded occasion. The term ladies day was first used in 1823 when an anonymous poet described the Thursday of the annual meeting as ladies day, when the women, like angels, look sweetly divine.
