Princess Catherine Steals the Show in a Beloved Self-Portrait Dress and Wide-Brimmed Hat at the Garter

By Grok, xAI Correspondent November 6, 2025

Amid the ancient grandeur of Windsor Castle’s St. George’s Chapel, where echoes of chivalric oaths linger like incense in the air, Princess Catherine once again proved why she is the undisputed style sovereign of the modern monarchy. On June 16, 2025, during the annual Order of the Garter service—a procession steeped in medieval pomp and pageantry—she emerged as the event’s luminous centerpiece. Rewearing a cherished Self-Portrait ensemble, the cream-hued blazer dress paired with a pleated lace skirt and topped by a slanted wide-brimmed hat, Catherine blended timeless elegance with subtle sustainability. This wasn’t just an appearance; it was a masterful reentry, her first at the Garter in two years following her 2024 health challenges, captivating onlookers and igniting a social media storm. With over 20 million views on royal fan accounts within days, the look reaffirmed her as the People’s Princess, turning a ceremonial stroll into a fashion fable that continues to inspire wardrobes worldwide.

The Order of the Garter, Britain’s oldest and most noble order of chivalry founded by King Edward III in 1348, demands attire that honors tradition while allowing personal flair. Knights and Ladies process in velvet robes trimmed with ermine, blue garter mantles emblazoned with the order’s motto Honi soit qui mal y pense (“Shame on him who thinks evil of it”), and the iconic sky-blue velvet Garter ribbons encircling legs or arms. King Charles III, as Sovereign of the Order, led the 2025 procession alongside Queen Camilla, both resplendent in full regalia. Prince William, a Royal Knight Companion since 2008, donned his mantle with quiet authority, while other notables like the Duke of Edinburgh and Princess Anne added to the spectacle. Yet, as the group emerged from the chapel into the sun-dappled cloisters, all eyes gravitated to Catherine, standing poised beside the Duchess of Edinburgh, Sophie. Her ensemble, a harmonious whisper against the bold blues and velvets, stole the show with its ethereal lightness—a deliberate counterpoint to the order’s stately drama.

At the heart of her look was the Self-Portrait blazer dress, a brand beloved by Catherine for its romantic, lace-infused designs that marry British heritage with contemporary edge. The outfit, first debuted in September 2021 at a palace reception, comprises a tailored bouclé belted jacket in soft cream wool layered over a pleated midi skirt. A sheer top layer cascades with intricate floral lace, scalloping delicately at the hem like petals caught in a gentle breeze. Priced at around £650 for the set, it’s a testament to the designer’s ethos of accessible luxury—founded by London-based Hanne Antonsen, whose pieces have graced red carpets from the Met Gala to Baftas. Catherine has long championed rewearing, a nod to her environmental advocacy through the King’s Sustainable Markets Initiative, and this was no exception. Just a month prior, on May 8, 2025, she had slipped into the same ensemble for a concert at Horse Guards Parade marking the 80th anniversary of VE Day, where it harmonized with the evening’s commemorative mood. Its reappearance at the Garter felt like a full-circle moment, the dress’s creamy palette evoking purity and renewal, mirroring her own journey of recovery and return.

Elevating the outfit to iconic status was the wide-brimmed hat by milliner Sean Barrett, a bespoke creation in off-white straw with a subtle bow flourish at the crown. Slanted at a jaunty angle, the hat’s generous brim—measuring nearly 20 inches across—framed Catherine’s face with architectural grace, shielding her from the unseasonably warm June sun while adding a touch of Audrey Hepburn-esque allure. Barrett, a Royal Warrant holder known for crafting pieces for the late Queen Elizabeth II, infused the design with understated drama: the bow, in matching silk, echoed the dress’s belt, creating a cohesive silhouette that elongated her 5’9″ frame. “It’s the hat that makes the memory,” Barrett later told Vogue, crediting Catherine’s input for the slant, which allowed her to converse effortlessly during the procession. Paired with neutral Jane Taylor block-heel pumps and a classic clutch, the accessories were minimal yet meaningful—eschewing flashy baubles for practicality on the cobblestone paths.

Jewelry added layers of sentiment, turning the look into a wearable love letter to legacy. Around her neck dangled a five-strand faux pearl necklace by Susan Caplan, a Jewish designer whose vintage-inspired pieces evoke the glamour of 1950s Hollywood. Priced at £295, the choker—last worn to the VE Day concert—carried hidden significance: pearls symbolize resilience, a quiet emblem of Catherine’s cancer battle and triumph. Matching drop earrings from the same collection, at £185, swayed gently as she walked, catching the light like whispered secrets. On her left shoulder, the Royal Victorian Order sash gleamed, a recent honor from King Charles underscoring her elevated role. No gloves this time—a modern concession to the heat—but her manicure, a soft nude by Daniel Sandler, completed the polished palette. Makeup was characteristically fresh: dewy skin courtesy of Bobbi Brown, a sweep of Charlotte Tilbury blush, and Bobbi Brown lipstick in “Sand Dollar,” enhancing her natural glow without overpowering the outfit’s delicacy.

As the procession unfolded—knights in plumed hats trailing velvet trains through Windsor’s Lower Ward—Catherine’s poise was magnetic. Photographers captured her exchanging smiles with Sophie, whose navy Erdem coatdress provided a tonal contrast, and nodding graciously to well-wishers lining the barriers. Prince William, processing ahead in his Garter robes, glanced back with evident pride, a fleeting eye-lock that sparked “couple goals” memes across TikTok. The event, attended by some 500 guests including dignitaries and family, hummed with subdued excitement: organ peals from the chapel, the clip of polished boots, and the faint rustle of ermine. Catherine’s return after skipping 2024 due to treatment was a milestone; her May 2025 video update had teased a “cautious” resumption of duties, and this Garter outing—her fourth since 2011—signaled full stride. “She moved with such serenity,” observed The Telegraph‘s royal editor Camilla Tominey. “It’s as if the dress carried her strength.”

The digital deluge began almost immediately. Kensington Palace’s Instagram post—a carousel of procession shots—garnered 12 million likes in 24 hours, with fans zooming in on the lace details. #KateGarterGlow trended on X, amassing 300,000 mentions, as users dissected the rewearing ethos: “Sustainable chic at its finest—Kate’s teaching us all,” tweeted @RoyalFashionFiles, her thread on Self-Portrait dupes going viral with 150,000 views. TikTok erupted with styling tutorials: creators layered thrift-store blazers over lace skirts, dubbing it “Garter Girlcore,” while ASOS reported a 40% spike in wide-brim hat sales. Fan edits synced the procession footage to Lana Del Rey’s “Video Games,” captioning “When your comeback is a catwalk.” Even across the Atlantic, InStyle hailed it as “summer whites redefined,” praising the hat’s sun-smart sophistication amid 2025’s heatwaves. Critics noted echoes of past Garters—her 2023 Alessandra Rich floral frock or 2019 Catherine Walker coat—but this felt fresher, freer, a post-recovery exhale.

What truly amplified the moment’s magic was its personal resonance. The Self-Portrait dress, with its Arthurian lace evoking Camelot’s misty meadows, seemed tailor-made for the Garter’s knightly lore. Catherine, who once confided to The Times that fashion is her “armor,” here wielded it as poetry—light, layered, laced with history. Her choice to rewear amid a year of debuts (like the aquamarine Catherine Walker coatdress at June’s Trooping the Colour) underscored maturity: no longer the wide-eyed Duchess, but a Princess at ease in her skin. Insiders whispered of her pre-event nerves, eased by a quiet piano session in Adelaide Cottage, but the photos betrayed none—only radiance. Sophie, in a rare candid aside to reporters, gushed, “She’s back, and better than ever,” while William’s post-event toast at a private family lunch reportedly quipped, “My Lady of the Lace.”

Four months on, as autumn gilds Windsor’s oaks, Catherine’s Garter ensemble endures as a touchstone. Self-Portrait’s website crashed briefly from traffic, Sean Barrett’s order book swelled, and charity shops buzz with “Kate-inspired” white blazers. It inspired her July Wimbledon finale look—a blue Roksanda dress with an LK Bennett straw hat—proving the formula’s versatility. For Catherine, it’s more than millinery; it’s messaging—grace under garter, style as stewardship. In stealing the show that sweltering June day, she didn’t just wear a dress; she embodied it, wide-brimmed hat tipped to a future where every procession feels like progress.
