The Duchess of Cambridge looked stunning in a polka dot dress as she channeled the style of her late mother-in-law Princess Diana.

Kate sported a $2,400 Alessandra Rich dress as she joined her husband Prince William in a carriage procession.

The mother-of-three also wore a Sally-Ann Provan black and white floral hat and Princess Diana’s pearl and diamond earrings as she arrived for day four of Royal Ascot.

Organizers of the event have announced that the dress code will not be enforced due to the soaring temperatures, with male attendees being allowed to remove their ties and jackets.

Guests arrived at the event wearing over-the-top head coverings, colorful dresses, and sparkling jewelry.

Prince William also appeared dashing in his suit he matched with a light blue patterned tie and hat as he arrived with his wife.

In the carriage, the Cambridges were joined by The Hon. Arthur Vestey and The Hon. Mrs. Vestey.

Peter Phillips and his girlfriend Lindsay Wallace, who wore a pink dress and a matching hat, occupied the second carriage.

The Duchess of Cambridge seemingly channeled the style of the late Princess of Wales in a dress almost identical to the one her mother-in-law wore 34 years ago.

Kate’s Alessandra Rich outfit mirrors the dress worn by Princess Diana to the Berkshire meeting in June 1988.

The mother-of-three also wore a flat top hat like her husband’s late mother did more than three decades ago.

She also wore a pair of pearl and opulent diamond earrings that had once belonged to Princess Diana.

The Royal Ascot has returned to its former pre-pandemic glory – with guests no longer deterred by Covid restrictions.
