Beatrice Borromeo and Tatiana Santo Domingo front row at Dior in Paris
Beatrice Borromeo took her front-row seat at the Christian Dior show during Paris Fashion Week on Tuesday, 29 September, with her sister-in-law Tatiana Santo Domingo beside her. The pair, who are sisters-in-law through marriage into Monaco's Casiraghi family, watched the show together from the front row. HELLO! Magazine
Borromeo chose a sharp, tailored look for the afternoon. Santo Domingo wore a long brown suede coat over a white shirt with black trousers and black shoes. It was classic front-row dressing. Understated, polished and built for photographs.
The outing carried extra weight. Dior's public relations director, Mathilde Favier, died in a car crash in August alongside her partner, film producer Nicolas Altmayer. Borromeo and Pierre Casiraghi attended Favier's funeral at the Eglise Saint-Sulpice in Paris on 31 August 2026.
Paris follows a busy September for the family. Borromeo attended Vogue World: Milano 2026 at the Galleria Vittorio Emanuele II in Milan on 22 September 2026. That is Vogue's travelling runway show, staged this year in Milan's famous glass-roofed arcade. In mid-September, Princess Alexandra of Hanover got engaged to Ben-Sylvester Strautmann.
For fans, this is what makes the pairing work. Borromeo is a regular at major fashion moments. Santo Domingo keeps a lower profile. Together in Paris, they gave photographers a rare joint appearance.
The Dior show is one of the anchor events of Paris Fashion Week, the twice-yearly series of designer presentations that closes the month-long fashion circuit. Borromeo and Santo Domingo stayed to the end, leaving together after the finale.
