Queen Elizabeth II’s second oldest grandchild Zara Tindall’s fashion ensemble at the Royal Ascot opening day held Tuesday has managed to turn many heads with her colorful dress.

Princess Anne’s daughter was just one of the ladies, who wore their best formal daywear attire at the Royal Meeting at the Ascot, People magazine reported. Tindall wowed royal fans with her Mary Katrantzou dress that featured a floral design of various colored blooms with striped lines across the flower patterns. The long-sleeved dress also had an oversized white cuff.

To accessorize, the accomplished equestrian wore simple jewelry, black pumps, as well as a yellow bag. To complete the look, Tindall wore a royal blue Rosie Olivia Millinery hat that featured a unique topknot design with a thin yellow accent ribbon. Some of the ribbon tendrils also extended up while a few wisps curled inwards. Tindall’s look was described as a style that “took a little more risk,” as stated in the same report.

Tindall’s Royal Ascot attire may seem excessive for some fashion fans, however, the annual racehorse meeting has also been known as a fashion event. The Royal Meeting at the Ascot even requires a strict dress code for its attendees. Gentlemen are required to wear a gray or black top hat, a tie, black shoes, as well as a suit with coattails, as indicated in the Royal Ascot’s website.

For the ladies, the length of dresses and skirts should reach just above the knee area or longer. Halters, spaghetti straps, off-shoulder and sleeveless tops are not allowed, as well as midriff-baring styles. Trouser suits can also be worn, although it should be full length and of matching color and material. Hats should also be worn; however, fascinators are not permitted. Ladies can also opt to wear a headpiece instead of a hat, provided that it meets the required solid base measurement of 4 inches or more in diameter.

Meanwhile, Tindall was accompanied by her husband Mike to the Royal Ascot opening day. The Queen and Prince Philip, as well as other members of the royal family also attended the event such as Prince Harry, Prince Charles and the Duchess of Cornwall.
