Meet Dior’s longtime PR director Mathilde Favier
Mathilde Favier was one of the most prominent figures in Paris’ fashion and social circles. She died on August 17, 2026, after being involved in a road accident in France. The same accident also claimed the life of her third husband, French film producer Nicolas Altmayer. French authorities revealed that the accident occurred in Aurvault in the Deux-Sevres region.
The couple’s vehicle collided with a truck when they were trying to overtake another vehicle. As of now, an investigation has already been opened to find out more about the circumstances of the crash.
Speaking about Mathilde, while she was not a household name when we compare her to traditional celebrities, she had immense power behind the scenes of the international fashion industry.
For several years before her death at 57, Mathilde would manage Dior’s relationship with global celebrities and ambassadors. She became one of the key links between the fashion house and the stars who would wear its creations.
Born and raised in Paris, Mathilde Favier actually came from a highly creative family. It is believed that her family also had deep connections to the fashion world. For instance, her half-sister, Victoria de Castellane, is Dior’s creative director of fine jewellery. Mathilde’s uncle, Giles Dufour, had a close working relationship with Karl Lagerfeld at Chanel.
Mathilde Favier entered the fashion industry when she was still in her early twenties. She first gained experience at Chanel before deciding to shift gears and move into public relations. Before she made a name for herself while working at Dior, Mathilde spent around 11 years at Prada. A report from Le Parisien reveals that she had been linked with Dior for roughly 14 years before her unexpected death.
Since Mathilde had worked closely with some of the biggest names in the entertainment industry, among her responsibilities at Dior were welcoming celebrities to their shows. She would coordinate their appearances and maintain relationships between the brand and its numerous ambassadors.
Back in 2024, Mathilde authored Living Beautifully in Paris, a coffee-table book that explored the city through her perspective. It also talked about the homes, lifestyles, and stories of her influential circle. The book, which was published by Favier, showcases Mathilde Favier as not only a renowned fashion executive but also a person who was deeply connected to Parisian art, design, gastronomy, and culture.
During an interview in Paris, Mathilde revealed that the book was 2 years in the making. She had also claimed that it was a fortune teller who predicted she would write a book at some point in her life. While she laughed at the idea back then, she realised that the prediction was true when she got the call from the publishing house.
About Mathilde Favier’s husband, Nicolas Altmayer
Speaking of Mathilde's husband, he co-founded Mandarin & Compagnie, formerly Mandarin Production, with his brother, Eric Altmayer, in 1996. Over the years, the company produced over 70 feature films.

Rest in peace, Mathilde Favier.
