There are two perfumes on the shelf of the bathroom where Pierre (Michel Piccoli) is shaving and Hélène (Romy Schneider) is putting mascara on. The white bottle with a floral pattern is the refillable atomizer of Guerlain Chant d’Arômes, created by Jean-Paul Guerlain and launched in 1962; the white and green striped box contains Carven Ma Griffe, a chypre floral perfume created by Jean Carles and launched in 1946.
