Ranked: 5 Best Dressed Royals at Peter Phillips and Harriet Sperling’s Wedding

Peter Phillips and Harriet Sperling's wedding may have been all about the happy couple, but the royal guests certainly gave everyone something to talk about. Sperling may have taken center stage in a breathtaking Emilia Wickstead wedding dress, but the guest list was equally packed with high-fashion inspiration. From Kate Middleton’s standout look to the most elegant ensembles of the day, here are the five best-dressed royals who defined wedding guest elegance over the weekend.

For the wedding, Princess Kate looked effortlessly elegant in a soft blush Roland Mouret dress that the designer describes as a "deep cream." The timeless design featured a folded collar, a belted waist, button detailing, and a flowing full skirt that felt perfectly suited to a summer church wedding. She completed the look with a coordinating boater-style hat and classic accessories—including Princess Diana's three-layered pearl bracelet—keeping her outfit polished yet understated. She once again proved why she remains one of the Royal Family's most reliable style icons.

Sophie, Duchess of Edinburgh, got the wedding dress code exactly right in a gorgeous pale blue Beulah London dress and matching hat. The soft shade felt made for a sunny summer wedding and immediately stood out among the crowd without being over the top. Sophie always knows exactly how to dress for her frame. By keeping her accessories minimal, she wisely let the exquisite tailoring of the dress speak for itself.

While Isabelle de la Bruyère may not be a household name, she absolutely proved she knows how to deliver a masterclass in royal wedding attire. The art expert, who is dating Princess Margaret's son David Armstrong-Jones, arrived in an elegant champagne-colored dress, perfectly accessorized with a wide-brimmed straw hat that seemed tailor-made for a sun-drenched day in the Cotswolds. While plenty of guests went for bright colors, Isabelle stuck to soft neutrals, and it paid off.

Lady Natasha Finch proved that you don't need bright colors or dramatic details to stand out. The Beulah London co-founder arrived in a pretty pastel look that felt effortlessly chic and perfectly suited to the countryside wedding setting, alongside her husband, Rupert Finch. Paired with a matching headpiece and minimal accessories, the outfit had that easy elegance that looks completely put together without seeming overthought. Moreover, the dress was also previously worn by Kate, who is a champion of his brand and has chosen to wear their pieces on numerous occasions.

Lady Sarah Chatto, Princess Margaret’s daughter, proved that classic black and white never goes out of style. For the event, she arrived in a chic monochrome look that stood out among the sea of pastels at Peter Phillips and Harriet Sperling's wedding. With its clean lines and understated elegance, the outfit felt effortlessly sophisticated and had a touch of old-school royal glamour about it.
