I think Xavier Dolan must have a thing for perfumes mothers wear. In his films, there’s often a moment in which the protagonist’s mother explains what perfume she’s wearing , so I guess this must have something to do with a personal obsession of the director. In this case, Grace (Susan Sarandon) is wearing Nina Ricci L’air du temps, the classic floral/spicy creation by Francis Fabron launched after WWII, in 1948.
 In Mommy, Diane says she’s wearing Christian Dior Eau Sauvage.
Amy (Emily Hampshire) checks her make-up in the compact mirror of Chanel Les Beiges Healthy Glow sheer powder.
Diane (Anne Dorval) wears a classic men’s perfume by Christian Dior – Eau Sauvage. She hasn’t bought it (most of the time she’s broke), but she’s using the leftovers of a bottle her uncle gave her. If she could buy perfume, she would probably wear something overtly sexy and feminine, but the Dior perfume strangely suits her. Her son Steve (Antoine-Olivier Pilon) loves it: “You smell like fucking heaven,” he comments.
Eau Sauvage, famous for its legendary fresh citrusy notes on a woody base, was created by Edmond Roudnitska and introduced in 1966.
Francis (Xavier Dolan) uses a L’Artisan Parfumeur perfume.
