There are three bottles of Oscar de la Renta Esprit de Parfum on Amber’s dressing table. This is likely to be a historically accurate choice: Oscar, the first perfume of Oscar de la Renta, was created by Jean-Louis Sieuzac and launched in 1977.
The Esprit de Parfum was launched in the 1980s, so it’s possible it was on the market in 1984, year in which the last scenes of the film are set.
