Kitty Hawkins (Amy Beth Hayes) and the girls at the cosmetics counter are ready to welcome Delphine Day (Polly Walker), a businesswoman and nightclub owner who’s the talk of the town: sexy and independent, she’s presenting her novel at Selfridges. Lots of Guerlain flacons bouchon coeur can be seen, including a giant factice bottle.
When Delphine stops by the counter, Kitty asks her if she wants to try a “new scent,” which happens to be Guerlain L’Heure Bleue.
This is historically accurate: the Jacques Guerlain creation was launched in 1912, two years before 1914, year in which this episode is set.
Delphine can’t help but loving it!
Kitty, who’s a skilled sales assistant, explains the composition of the perfume, a “floral bouquet” with notes of “bergamot, aniseed and a velvety base of vanilla and tonka bean.”
