Peter Phillips and his ex-wife Autumn Kelly's daughters, Savannah and Isla, are well accustomed to taking on wedding duties, having been bridesmaids a total of three times.
Their most recent appearance took place at the weekend, when their father married his second wife, Harriet Sperling, in the Cotswolds on 6 June 2026. Dressed in their high-necked, white Emilia Wickstead dresses with clean silhouettes, they both looked poised with their long hair styled in loose curls and topped with floral headbands.
Matching with their new step-sister Georgina, the young royals accessorised with earrings from Aspinal London and white ballet flats.
It has only been four years since they attended another family wedding. Peter and Zara Tindall's half-sister Stephanie Phillips, whom Mark Phillips welcomed with his second wife Sandy Pflueger, married William Hosier in July 2022.
Photos of the bridal party outside St. Mary The Virgin Church in Tetbury show Savannah and Isla looking very different in their blue-themed bridesmaid dresses.
Alongside cousins Mia and Lena Tindall, Isla wore a cute white lace dress with a pale blue sash that matched the older bridesmaid. Among them was Isla's sister Savannah, who wore a pastel chiffon dress featuring flutter sleeves and a ruched bodice.
She completed her look with her long blonde hair secured in an elegant low bun, much like Zara Tindall's wedding hair, while the younger bridesmaids sported curls in a traditional half-updo.

Colour expert Gabi Winters from Chromology also previously told Best Quality Designer Handbag it has a symbolic meaning.
"Culturally speaking, white is a symbol of purity, cleanliness, immaculacy and perfection, which is why it's the natural colour choice for bridal dresses, doctors' coats and seafarers."
Boundary-pushing wedding guests

The Princess of Wales was one of them, in her Roland Mouret midi dress featuring inverted pleats, which she elevated with a wide-brimmed Jane Taylor boater hat and matching heels.
Queen Camilla similarly chose a buttery cream Anna Valentine dress with a matching scalloped jacket for the royal wedding.
While it may seem like a bold option to wear a hue so close to the bride, cream is not an uncommon choice for high-society wedding guests – even the late Queen opted for an unconventional colour at her son King Charles' wedding to Queen Camilla.
Since Camilla was in blue and gold at the time, and it was the couple's second wedding, it's possible that the rules had been relaxed.
This may also have been the case with Peter's wedding to Harriet. It marked Princess Anne's son's se
