Making a case for pastel blue, the Princess of Wales delighted fashion fans all over the world at Trooping the Colour 2026. Sporting a new coat dress for the occasion, the 44-year-old looked resplendent in the Catherine Walker design, which had chic white detail at the collar. The regal style was elegant and strangely familiar on initial sighting.

Diana defied rainy conditions as she arrived at Huddersfield airport, wearing the icy blue ensemble.

In 2025, the brunette royal donned a patriotic, turquoise coat dress by Catherine Walker once again. Kate's stylish number was known as the 'Bria', and the brand described the striking design as a "deep aquamarine wool coatdress with ivory contrast lapels and cuffs."

Diana's love for Catherine Walker
Catherine Walker was considered one of Diana's favourite labels. The blonde royal wore the brand throughout her royal career and owned over 1,000 styles by the designer. Catherine also memorably designed the black dress that Diana was buried in at Althorp.
Said Cyrus, who founded the company with his wife, Catherine Walker, told HELLO! in 2017, "We saw our job as giving Diana the tools of her trade.

Diana was always very polite, very courteous and very appreciative. She was never late for an appointment, which, for a busy person, shows respect, and whenever she wore a dress that was admired, she'd thank us," he revealed.
