It wouldn't be Chelsea Flower Show without spotting a few national treasures perusing around the gardens, and this year Dame Mary Berry was back enjoying the opening day of the 2026 show. On Monday (18 May), Dame Mary joined the press preview to explore what's on offer, ahead of her BBC special later this week.

For the occasion, Dame Mary chose a pale pink shirt dress with a pleated midi skirt, and we couldn't help but notice the resemblance to one of the Royal Family's most popular choices. Dame Mary's dress featured a polka dot print, which is one of the most recognisable patterns worn by the Princess of Wales. Kate leans on the print often, particularly when attending Wimbledon. The long sleeves, fitted waistband and understated design of Dame Mary's dress also channel the style of dress which Kate has become almost synonymous with.
