The Princess of Wales decided at the last minute not to attend Royal Ascot 2025, as she continues to find the right balance following her battle with cancer.

The 43-year-old Princess was said to be disappointed at not attending the famous horse racing event in Berkshire with her husband and the King and Queen.

Although we were very sad not to see our favourite royal, who we know would have shone in the style stakes, we decided to take a look at her past Ascot look. One in particular stood out as the ideal number to wear in 2025.

In 2023, Kate sported a rather radical frock. Disregarding the pastel colourway which is often embraced in the summer months, the royal wore a bright red midi dress from Alexander McQueen which boasted cuffed gigot sleeves, a 'midaxi' length and a collared neckline. The dress was paired with a wide-brimmed hat from royal favourite milliner Philip Treacy and red court pumps.

This dress would be perfect for 2025, as vibrant, cherry red tones have been all over the catwalks this year.

Kate's best Ascot looks

The mother-of-three has always dressed impeccably for Ascot over the years, stepping out in a variety of delightful styles.

Kate debuted at the world-famous racecourse in 2016 and in that time has worn lace gowns and ruffled polka-dot dresses to the event.

Looking dazzling in white, the then-Duchess of Cambridge played it safe for her Ascot debut, wearing a simple yet stunning Dolce & Gabbana lace ensemble.

Ensuring her look fit with the festivities, the royal added a £1,050 Una hat by Jane Taylor millinery.

Just one year later, many remarked that the Princess paid homage to her fairytale wedding gown in a bridal-white lace dress designed by Sarah Burton for Alexander McQueen. She paired it with a feather-adorned cocktail hat and pearl earrings.
