A royal walk with a quiet message
Kate Middleton stepped out on Christmas morning at Sandringham with the rest of the royal family. While greeting crowds during the annual December 25 walk to St. Mary Magdalene Church, she wore a brown tartan Blazé Milano coatdress paired with a chocolate fascinator by Juliette Botterill Millinery and suede boots by Gianvito Rossi. But the real attention grabber was her Cartier Trinity hoop earrings, valued at $4,000.
Princess Diana was also a Cartier fan and famously wore a Trinity ring on her pinky finger. Kate Middleton’s choice to accessorize her outfit with the Trinity hoops feels like a chic whisper to the past, tying her to her late mother-in-law. This quiet fashion gesture has a deeper backstory than meets the eye at first glance. 
Earrings with a story
Kate Middleton first debuted these Trinity earrings in January 2025, right around her January 9 birthday. Many believe Prince William gifted them for her 43rd birthday. The Trinity collection features white, yellow, and rose gold bands intertwined like a symbol of the past, present, and future.
Tatler also reported that the design represents love, loyalty, and friendship, which makes it an extra especial choice for the Princess of Wales. Interestingly, she also wore this exact Blazé Milano coatdress during a January visit to The Royal Marsden Hospital, and on that same date, January 14, she announced she was in remission. Wearing the same outfit to close 2025 feels like a full-circle moment.
Kate Middleton keeps Princess Diana’s earring legacy alive 
Kate Middleton has a history with Cartier and with the Trinity line itself. She wore a necklace from the collection back in 2012 while visiting the National Portrait Gallery and then again during a 2014 trip to New York City. She even wore another pair of Trinity earrings in 2016 at a banquet celebrating SportsAid’s 40th year. Meanwhile, Princess Diana, who passed away in 1997, made the Trinity look iconic. Now Kate is subtly turning it into her own signature move, one pair of hoops at a time.
