Mathilde Favier, the radiant force behind Dior’s public relations for years, left an indelible mark on Paris fashion with her warmth, sharp eye, and unshakeable joie de vivre.

She was known for her close friendships with figures across film, fashion, and society, and for authoring a personal guide to living beautifully in Paris.
Her family life began with her first marriage to American financier Robert Agostinelli, co-founder of the private equity firm Rhône Group. The couple married in Venice and welcomed two children. Though the marriage ended, Favier often spoke of Agostinelli as a wonderful father. She later remarried and, in recent years, shared her life with film producer Nicolas Altmayer. Through every chapter, her bond with Héloïse and Carlo stayed strong and visible—photos of them together frequently appeared on her social media, showing a mother who prioritized presence alongside her professional intensity.
Héloïse Agostinelli: Model, Style Presence, and Family Anchor
Héloïse, the elder of the two, has followed a path that blends her mother’s fashion world with her own independent presence. Now around 28, she has worked as a model and previously appeared on the British reality series Made in Chelsea. She has fronted beauty campaigns and maintains a polished yet approachable public image that feels like a natural extension of the elegant French aesthetic her mother embodied.
Those who know the family describe a close mother-daughter relationship built on shared tastes, quiet support, and mutual admiration. Héloïse has long been part of the Paris social and fashion scene, often appearing at events alongside Mathilde. In the days following the tragedy, the family’s emphasis has been on holding one another close, with Héloïse standing as a steady presence for her younger brother.

What has stood out most recently is the deeply personal tribute Carlo shared after his mother’s death.
