While Mary (Erin Darke) and Midge (Rachel Brosnahan) are walking through the beauty department, some perfume bottles can be seen on the counter on the left: they’re Madame Rochas by Rochas (created by Guy Robert in 1960) and a flacon abeilles dorées by Guerlain.

Doesn’t The Marvelous Mrs. Maisel take place in 1958? Madame Rochas wasn’t released until 1960. (Sorry, I’m a vintage perfume lover. Just being prickly. 😉
Looks like lots of original White Shoulders by Evyan products down in the glass case on the right.
