The British royal family’s annual Christmas traditions at Sandringham Estate have long been a highlight of the festive season, offering rare glimpses of the Windsors in a relaxed, family-oriented setting. On December 25, 2025, the gathering once again drew crowds of well-wishers and royal enthusiasts eager to catch a glimpse of the royals walking to St Mary Magdalene Church for the traditional service. Among the arrivals, Catherine, Princess of Wales, once again captured hearts and headlines with her elegant, thoughtful choice of attire — a breathtaking cornflower-green Elie Saab ensemble paired with a sculptural Philip Treacy hat that royal fashion observers are already calling one of her most refined looks to date.
The Princess of Wales, who has been gradually returning to public duties after a challenging period of health recovery, appeared radiant alongside Prince William and their three children — Prince George, Princess Charlotte, and Prince Louis. The family’s arrival at the church was met with warm cheers from the thousands who lined the path, many braving the crisp Norfolk winter to offer flowers and well-wishes. Catherine’s outfit, a sophisticated and feminine choice, perfectly balanced festive tradition with timeless elegance, reinforcing her reputation as one of the most consistently stylish members of the royal family.
The cornflower-green Elie Saab dress, featuring delicate sheer sleeves and intricate detailing, was a vision of understated glamour. The soft, ethereal blue-green hue evoked the serenity of spring even in the heart of winter, while the sheer sleeves added a romantic, almost ethereal touch. The dress itself was a bespoke creation, drawing inspiration from Elie Saab’s Resort collections, known for their romantic silhouettes, luxurious fabrics, and intricate embellishments. Catherine has long favored the Lebanese designer for formal daytime events, having previously worn similar Elie Saab pieces to Royal Ascot in 2019 and a Buckingham Palace garden party in 2023. On those occasions, she also paired the look with a signature Philip Treacy hat, proving once again her love for re-wearing and re-styling favorite pieces with subtle variations.
The Philip Treacy hat, a sculptural wide-brimmed design in a matching cornflower shade, featured a delicate floral detail that added a touch of whimsy without overwhelming the overall look. Treacy, a milliner favored by the late Queen Elizabeth II and many other senior royals, has long been one of Catherine’s go-to hat designers. His creations are known for their architectural elegance and impeccable craftsmanship, and this particular hat — with its clean lines and subtle embellishment — perfectly complemented the dress’s romantic yet regal aesthetic. The floral accent, understated and refined, echoed the natural beauty Catherine has so often celebrated in her public messaging, particularly through her “Mother Nature” video series.
Accessories were kept minimal yet meaningful. Catherine completed the ensemble with classic nude pumps, simple pearl earrings, and a discreet clutch, allowing the dress and hat to remain the focal points. Her hair was styled in soft waves, falling just below her shoulders, and her makeup was natural and glowing, emphasizing her warm smile and the quiet confidence she has displayed throughout her recovery.
The Sandringham Christmas Day walkabout is one of the few occasions each year when the royal family interacts directly with the public in a relatively informal setting. Crowds gather along the path to the church, offering gifts of flowers, cards, and homemade treats, and the royals spend time greeting well-wishers and posing for photographs. Catherine’s presence on this day was particularly meaningful. After a year marked by her cancer diagnosis, treatment, and gradual return to public life, her appearance at Sandringham was seen as a powerful symbol of resilience and hope. Fans lined the route, many holding signs that read “We love you, Catherine” and “You’ve got this,” reflecting the deep affection and support she has received from the public.
Royal fashion watchers were quick to praise the outfit as one of Catherine’s most elegant to date. The cornflower-green hue was widely interpreted as a subtle nod to renewal and hope — colors often associated with spring and new beginnings — while the choice of a designer like Elie Saab, known for his romantic and feminine aesthetic, underscored her consistent preference for pieces that are both sophisticated and approachable. The Philip Treacy hat, with its sculptural shape and delicate floral detail, added a touch of artistry that elevated the entire look.
Insiders note that Catherine’s style choices have always been intentional, often reflecting her personal values and the broader message she wishes to convey. In recent years, she has increasingly favored re-wears and sustainable fashion, a practice that aligns with her commitment to environmental causes and conscious consumption. The cornflower-green Elie Saab dress, previously seen in variations at high-profile events, was a perfect example of this philosophy — a beloved piece given new life through careful styling and the addition of the Treacy hat.
The Sandringham Christmas Day tradition dates back over 160 years, when Queen Victoria first made the Norfolk estate the royal family’s preferred Christmas retreat. The walk to church, followed by a private family lunch at Sandringham House, remains one of the few occasions when the royals appear together as a family unit in a semi-public setting. In 2025, the gathering included King Charles III and Queen Camilla, the Prince and Princess of Wales and their children, and other members of the extended family, creating a warm, festive atmosphere despite the challenges of recent years.
Catherine’s appearance on this day was widely seen as a triumphant return to form. After months of limited public engagements, her radiant smile, poised demeanor, and stunning outfit signaled strength, grace, and a renewed sense of purpose. Fans and royal commentators alike praised her ability to balance tradition with modernity — honoring the occasion while remaining true to her personal style.
As the royal family gathered for lunch and private celebrations, the image of Catherine in her cornflower-green Elie Saab dress and Philip Treacy hat lingered in the minds of millions. It was more than a fashion moment; it was a quiet declaration of resilience, elegance, and hope — qualities that have defined her throughout her time as a member of the royal family and that continue to inspire people around the world.
