Marion Steiner is a strong woman: she’s the owner and leading actress of the Théâtre Montmartre in Paris during WWII. She’s also exceptionally beautiful and elegant, despite the harsh living and working conditions of that historical period. Still, it’s quite surprising to see an incredible array of Lanvin Arpège  products on her dressing table. This choice is historically accurate: the Lanvin perfume, created by Paul Vacher and Andre Fraysse, was launched in 1927.
Starting from the left, there’s a tall faceted bottle of Eau de Lanvin Arpège.
Next, two small bottles with square stopper of Arpège.
The only non-Lanvin product is Caron Narcisse Noir in the original bottle with engraved black stopper.
The black rectangular half-open box contains Lanvin Arpège soap. The packaging of the box seen in the movie is slightly different from the one above, though: the box in the movie has faceted – not rounded – edges.
The round box contains Arpège dusting powder.
Last, Arpège in the classic boule noire with ribbed stopper.
The same objects appear in a scene where Marion (Catherine Deneuve) is sitting at her vanity. In this case, another bottle of Eau de Lanvin Arpège can be seen in front of the mirror.
 Other Lanvin perfumes were launched before 1942 (year in which the film takes place) – Mon Péché in 1924, Scandal in 1931, Rumeur in 1934, Pretexte in 1937. The same bottles were used for most of them, so those seen on Marion’s table could contain one of them and not Arpège. Arpège was the most popular, though, so I guess it was easier to find in war times.
