Beatrice Borromeo steals the show at Dior’s Cruise show in Rome

But it has been Dior that has seen the most fruitful collaborations with Beatrice, a former political journalist who once spoke to Tatler about her biggest scoop. Most recently, at the 2025 Rose Ball, the royal wore a gown from the House to pay tribute to her husband’s grandmother, Grace Kelly.

With its cascading pleats and statement sleeves, the dress looked strikingly similar to one of the most iconic gowns in the fabled wardrobe of Princess Grace of Monaco – who founded the Rose Ball back in 1954 to support humanitarian projects. Emphasising the showstopping outfit, Borromeo wore a set of classic Tiffany jewels, opting for a necklace, brooch, and earrings from the jeweller’s ‘Bird on a Rock’ line.

The gown bears a resemblance to a piece that Grace Kelly wore to the Red Cross Ball in 1976, where she was joined by her daughter, Princess Caroline. Even that outfit, however, appeared to harken back to one dress in particular, from one of Kelly’s most notable starring roles.
