Harriet paired this with a matching skirt that stuck the ideal balance between modern chic and timeless formality.

Completing the look was a wide-brim ivory hat adorned with a single blossom, with her new siter in law to be, Zara Tindall, sweetly stepping in to steady it as the pair mingled near the paddocks.

Harriet finished her ensemble with understated beige pumps and delicate accessories, allowing the clean lines of her outfit to speak for themselves.

It was, in every sense, a study in discretion. Unlike some of Ascot’s louder fashion moments, Harriet’s look never shouted for attention.

Instead, it whispered sophistication—an approach long embraced by Princess Kate. 

The Princess of Wales, 43, is a global fashion icon renowned for mastering the art of looking regal without ever appearing overstated, and Harriet’s look bore an uncanny resemblance to her style.

Harriet’s decision to lean into subtlety rather than spectacle showed an instinctive understanding of royal dressing.

By choosing clean tailoring and a neutral palette, she ensured her ensemble carried quiet authority, a choice that felt polished yet never forced.

Much like Kate, she demonstrated that true style is not about dazzling theatrics, but about refinement, restraint, and the confidence to let simplicity shine.
