Funeral services for Mathilde Favier, the Dior PR executive who died earlier this month, have been set for Monday at 2:30 p.m. at the Church of Saint-Sulpice.

It is the second largest church in the French capital.

Also a renowned tastemaker and society figure, Favier was 57 when she died Aug. 17 in a car accident that also claimed her companion, French film producer Nicolas Altmayer.

Over her long career at Dior, most recently as international PR director for Dior women, Favier forged close relations with celebrities ranging from Rihanna and Jennifer Lawrence to Jisoo, but also a wide swath of top editors, LVMH Moët Hennessy Louis Vuitton executives and industry stakeholders.

She was adored for her infectious smile, positive attitude, professionalism, and passion for what the French call art de vivre.

In recent years she became a well-known figure on social media, her fame propelled by her hit 2024 coffee-table book “Living Beautifully in Paris.” Her Instagram account boasts 272,000 followers, having gained some 30,000 followers since her passing.

The half-sister of Victoire de Castellane, creative director of Dior jewelry, Favier moved in fashion circles since her teens, when her uncle Gilles Dufour got her an internship at Chanel, where he worked alongside Karl Lagerfeld.

Born and raised in Paris, she attended the Institut de l’Assomption, commonly known as Lübeck, where her classmates included designers Vanessa Seward and Camille Miceli, and stylist Emmanuelle Alt.

Favier cut short her studies to join Glamour magazine before eventually moving into public relations at Prada and then Dior, where she logged 15 years, straddling several creative directors.

“We all owe so much to her work and dedication. She brought such warmth, energy and was the most positive and uplifting person I have ever met,” Jonathan Anderson, Dior’s current creative leader, said of her passing. “Mathilde was the very embodiment of elegance and in many ways, the spirit of couture itself.”
