As the Princess of Wales stepped out for this year’s Trooping the Colour she was a vision in aquamarine with Princess Charlotte by her side, a mirror image in miniature.

Dressed in complementary outfits, the mother-daughter duo made a striking statement of unity and style.

When Kate and Charlotte match, it’s never an accident. Subtle yet deliberate, traditional yet modern – and increasingly a signature style move from the most fashionable pair in the House of Windsor.

The Princess of Wales, ever the master of sophisticated symbolism, chose a pale aquamarine coat dress by one of her go-to designers Catherine Walker. It was quintessential Kate, understated, graceful and impeccably regal.

Charlotte, now nine and confidently taking on more public appearances, echoed her mother’s palette with a sweet puff-sleeved dress in a slightly lighter shade but with the same contrasting white panels. The result? A harmonious pairing that exuded poise and togetherness without veering into gimmick.

Even their accessories were in sync. Kate’s wore statement hat, an elegant Juliette Botterill creation, with her hair in a sophisticated updo, while Charlotte’s was neatly swept back.

It wasn’t a full-blown fashion copycat moment, but twinning with tact, the sort of subtle coordination that tells a deeper story than any single outfit ever could.

Opting for aquamarine at Trooping The Colour, Kate wore a dress coat with ivory lapels and cuffs by Catherine Walker. Ever the fan of a good accessory, she completed the look with a wide-brimmed Juliette Botterill hat topped with a sculptural flower. Charlotte echoed her mother’s palette in a light blue dress with a crisp white band at the waist

Charlotte and Kate also wore coordinating outfits at Trooping the Colour in 2024. Princess Kate opted for a white ribbon dress featuring navy accents by Jenny Packham, which she paired with a Philip Treacy hat. Meanwhile Charlotte wore a navy dress with white ribbon detailing, essentially her mother’s outfit in reverse – and both completed their looks with white pumps

The Princess of Wales looked striking in an Alexander McQueen emerald coat on Christmas Day in 2024. She paired it with a green and navy tartan scarf which complemented daughter Charlotte’s plaid look and a matching Gina Foster hat in the same shade as Charlotte’s Beulah velvet hair bow

It was another matching moment for Princess Charlotte and the Princess of Wales at the coronation of King Charles. Charlotte wore a delicate silver bullion and crystal flower crown by Jess Collet and Alexander McQueen. Her mother also chose an intricate diadem by the designer in lieu of a tiara

Mother and daughter looked almost identical in matching black coat dresses complete with deep pleats at the back, at Queen Elizabeth II’s funeral. Complementing the similar silhouette coats were matching wide-brimmed hats, upholding the family tradition of fine millinery

Stepping out for the Easter Day service in 2022, Kate and Charlotte coordinated in pale pastel blue shades. Kate Middleton’s cinched Emilia Wickstead coat dress matched the robin’s egg blue of Charlotte’s Rachel Riley smocked frock, while the darker accent colour of her Jane Taylor headband complemented her daughter’s cardigan

The Princess of Wales took a more subtle approach to her coordinating looks with Charlotte for Christmas Day in 2019. Whilst the little royal was dressed in an Amaia forest green coat, and Kate wore a grey Catherine Walker, it was Kate’s accessories in the same shade of green that pulled their looks together perfectly

When attending Trooping the Colour in 2018, less than two months after giving birth to Prince Louis, Kate made a statement in a baby blue Alexander McQueen dress and coordinated Juliette Botterill hat, matching with Princess Charlotte who was dressed in a smock dress in a similar shade

At Trooping the Colour in 2017, Kate Middleton stunned in a peony-pink Alexander McQueen dress and Jane Taylor hat in a similar hue. Princess Charlotte was also in pink, wearing an adorable smock dress

This isn’t the first time we have seen the mother-daughter duo echo each other’s style, striking a harmonious sartorial chord.

Take last year’s Trooping the Colour. The pair turned heads with a masterclass in reverse twinning. Kate chose a structured white ensemble with navy detailing, while Charlotte wore navy with a white trim.

It was clever, dignified and delightfully endearing. Not too obvious or staged, but just enough to make a statement.

Even during more relaxed public appearances, such as the royal family’s traditional Christmas Day walk to church in Sandringham, the duo often display subtle styling synchronicities.

Matching coats, accessories in the same accent colours, or shades of the same hues are part of their repertoire. It’s never flashy or forced, just quietly in tune, like a mother and daughter in perfect harmony.

Of course, it’s more than just a sweet fashion moment. For Kate, who has become a modern icon of royal style, these outfits are statements.

Clothing isn’t just about looking good, it’s about sending messages. And what better message to send than one of unity, family and gentle succession? It humanises the monarchy in a way few other moments can.

Ultimately, these moments are joyful. There’s no denying the delight of seeing Charlotte walking in step with her mother, dressed in matching colours.

Because when the moment is big, a coronation, a jubilee, or a birthday parade, the Wales women match. And when they do, they remind us what the modern monarchy does best, tradition with a twist, duty with dignity and a splash of carefully considered style.
