Kate Channels Diana in Baby Blue at Trooping the Colour

The Princess of Wales arrived at Trooping the Colour 2026 on Saturday in a baby-blue Catherine Walker look that echoed Princess Diana, per Harper's Bazaar. Royal watchers also clocked her sentimental pearl earrings, which nodded to Diana while endorsing a major summer jewelry trend, Glamour reports.

The choices come as Kate continues a measured return to public life. The soft blue palette and pearl detailing have long been read as Diana shorthand, and the looks drew immediate buzz online. The King's birthday parade is among the year's most-watched royal showcases. Every accessory reads as a message -- and Kate's kept the late princess part of the moment.
