Baby blue Catherine Walker. Philip Treacy. The Irish Guards brooch. Cassandra Goad earrings. And five members of a family dressed in the same palette. The Princess of Wales did not disappoint. She did something considerably more interesting than that.
I predicted Catherine Walker. I predicted the Irish Guards connection. I predicted inherited jewellery. I predicted Princess Charlotte would echo her mother’s palette.
I was right on every count. I am not, for once, going to pretend that surprises me.
What I did not predict was the precise register she would choose. That is where today became genuinely interesting. Last year’s Trooping brought aquamarine, a colour with depth and authority, a shade that reads as considered and serious from every camera angle on the Mall. Today she wore baby blue. Pastel. Soft. Deliberately lighter than last year, deliberately lighter than the uniform of the regiment she colonels. The choice is not an accident. The choice is never an accident. But the direction of the choice, toward softness rather than authority, tells you something worth examining.
The coat dress was new Catherine Walker, baby blue with contrasting white piping along the edges. Underneath, just visible as she moved, a white dress. The layering is a Walker signature. Structure over softness, the coat providing the formality while the dress beneath adds a glimpse of something less armoured. The silhouette photographs cleanly from every angle, which matters enormously at an event designed to be photographed from every angle. The hat was Philip Treacy, wide brimmed, matching the coat precisely. No deviation. No contrast. A single coherent palette from hat to hem.
The Irish Guards brooch was pinned to the lapel. It is always there. It will always be there. She has worn it at every Trooping since becoming the regiment’s Colonel, and its presence has moved from gesture to statement to something approaching institution in its own right. The brooch is no longer a nod to her role. It is the visual shorthand for it.
The earrings require their own sentence. She wore Cassandra Goad pearl flower drops, pieces she first wore to Prince Louis’s christening in 2018. Not inherited jewellery this year. Her own. Pieces she chose eight years ago and has kept returning to ever since. There is something quietly significant about that choice on a day when she could have reached for any number of more historically weighted pieces. She reached for her own history instead.
Now consider the family around her. Prince George in a suit with a baby blue tie. Prince Louis in a matching baby blue tie. Princess Charlotte in a white dress with blue detailing. Five members of a family dressed in a single coordinated palette, the effect visible from the carriage, from the balcony, from every photograph taken on the Mall today. This is not coincidence and it is not maternal instinct. It is direction. Someone decided this family would present as a unified visual statement today. The woman most likely to have made that decision is the same woman who wore the coat dress.
The Diana comparison was inevitable and the press duly made it. Baby blue with white piping does echo certain Diana appearances, and Catherine Walker was Diana’s designer of choice throughout the 1980s and 1990s. Whether the echo is deliberate or simply the consequence of working repeatedly with the same house is a question only one person can answer. What I will say is this: the Princess of Wales has never appeared at Trooping the Colour without an awareness of the women who stood on that balcony before her. The echoes are never accidental. They are simply never explained.
Before today I predicted she would say something. She always does. What she said today, in the language of baby blue and white piping and coordinated children and her own pearl earrings, was something rather specific: we are a family, we are settled, we are well, and we are here.
After the years this family has navigated, that is not a small statement. It is, in fact, rather a large one.
