Kate Middleton Honors Princess Diana With An Elegant Nod To Her Iconic 1987 Look At Trooping The Colour

In a heartfelt fashion tribute that beautifully bridged generations, the Princess of Wales once again paid homage to her late mother-in-law, Princess Diana, during the 2026 Trooping the Colour ceremony on June 13. Kate Middleton stepped out in a elegant baby blue ensemble by Catherine Walker — Princess Diana’s longtime favorite designer, closely echoing a memorable look Diana wore in Easter 1987.

The Princess of Wales wore a tailored baby blue coatdress with crisp white trim and distinctive pocket details, paired with a coordinating hat by Philip Treacy. She accessorized the look with pearl Cassandra Goad earrings (previously worn at Prince Louis’s christening in 2018) and her Irish Guards Brooch, reflecting her role as honorary Colonel. The soft

powder blue hue, clean lines, and refined tailoring created a striking visual parallel to Diana’s 1987 outfit.

This is not the first time Kate has drawn inspiration from Diana at Trooping the Colour. In 2025, she wore an aquamarine and ivory Catherine Walker coatdress that referenced a 1992 Diana look from her India tour. Fashion experts note that Kate’s tributes have become more intentional and confident over the years, reflecting her growing comfort in her role as the future Queen.

A Modern Twist on a Classic Royal Look

While Kate’s 2026 ensemble closely mirrored the color, designer, and structural details of Diana’s 1987 look, she gave it a contemporary refresh. The silhouette was sleeker and more modern avoiding 1980s power shoulders or overly dramatic volumes making the tribute feel relevant for today while honoring the past.
Bethan Holt, fashion director at The Telegraph, previously explained that Kate uses fashion to celebrate Diana positively, “She brings it right up to date… She makes it her own without looking like she’s playing ‘dress up as Diana.’”

Trooping the Colour, the annual public celebration of King Charles’s birthday, is one of the most high-profile events in the royal calendar. Kate’s choice of outfit carries deep emotional weight, especially as she continues to balance public duties following her health journey. By channeling Diana, Kate reinforces the enduring legacy of the People’s Princess while establishing her own distinct style identity.

This baby blue Catherine Walker moment has already sparked widespread admiration across social media, with royal fashion watchers praising the thoughtful continuity between the two Princesses of Wales. It serves as a elegant reminder that fashion can be a powerful tool for remembrance and connection within the royal family.

Kate Middleton’s 2026 Trooping the Colour appearance not only honored Princess Diana’s iconic 1987 style but also showcased the Princess of Wales’s mastery of blending heritage with modernity. In doing so, she delivered one of the most poignant and stylish royal fashion moments of the year.
