Kate Middleton wore a tartan coatdress with Cartier Trinity earrings while attending Christmas Day church service in Sandringham on December 25, 2025.
Kate Middleton, the Princess of Wales, joined the royal family for the traditional Christmas Day church service at Sandringham in Norfolk on December 25, 2025. For the occasion, she chose a brown tartan Blazé Milano coatdress, styled with a chocolate-brown fascinator by Juliette Botterill Millinery, a patterned silk scarf from Really Wild Clothing, Gianvito Rossi brown suede boots, and her Cartier Trinity hoop earrings, estimated to be worth around $4,000.
The tartan coatdress grounded the look in classic royal tradition, with its structured, double-breasted silhouette lending a sense of formality and grace. Seasonal accessories like the fascinator and scarf added warmth and texture, while the suede boots struck a balance between elegance and comfort for the winter setting. Her Cartier Trinity earrings brought deeper symbolism to the ensemble, subtly nodding to Princess Diana, who famously favored the design. The three interlocking bands — representing past, present, and future — felt especially meaningful for an end-of-year royal appearance.
Notably, Kate’s outfit carried personal significance. She previously wore the same coatdress earlier in 2025 during her public message announcing her remission following cancer treatment, giving the look an added layer of continuity and quiet strength. As she continues to gradually return to royal duties and public engagements, her appearance at Sandringham was widely seen as a reassuring sign of stability and renewal. The earrings, believed to be a gift from Prince William, further highlighted the personal touches woven into this carefully chosen Christmas look.
