Taking to her Instagram page to share a picture from the annual event, the 58-year-old wrote: "So proud of my girls...Beatrice and @princesseugenie #royalascot @hrhthedukeofyork @ascotracecourse."

Beatrice, 29, and Eugenie, 28, joined their father Prince Andrew and grandmother the Queen as they entered the racecourse in a traditional horse-drawn carriage procession - as shown in the picture. For the outing, Beatrice picked a gorgeous black and white dress by Jonathan Simkai and teamed it with a matching saucer hat by Sally-Ann Provan. Her sister wore a beautiful high-necked floral dress by designer-of-the-moment, Erdem, and paired it with a boater hat, also by sally-Ann Provan.

At the moment, the royal family are preparing for Eugenie's wedding to fiancé Jack Brooksbank. The happy couple announced their engagement in January, and are set to tie the knot on 12 October at St George's Chapel in Windsor, just like the Duke and Duchess of Sussex. It is likely that the royal bride-to-be will follow in her mother's footsteps by wearing the York Diamond Tiara, which was given to the Duchess of York by the Queen and the Duke of Edinburgh before her nuptials to Prince Andrew. Close friends of the couple and senior members of the royal family will all gather in Windsor in four months' time for the upcoming nuptials.
