Kitty (Amy Beth Hayes) and Jessie (Sai Bennett) are collecting money for the Belgian Relief Fund, an international organization that supplied food to occupied Belgium and northern France during WWI.
Their counter is basically a display for Guerlain bottles.
Many of them are flacons abeilles, first used in 1828 to house the Eau de Cologne Impériale. The classic version of this bottle have the bees simply painted in gold enamel, while those with gold front label are the flacons abeilles dorées.
There are two flacons bouchon coeur, too. The choice is historically accurate because they first appeared in 1912; too bad one of these is a spray bottle, clearly not available at the time in which the tv show is set.
Last, there’s a flacon quadrilobe, another historically accurate choice because this bottle first appeared in 1908 to house the perfume Rue de la Paix, then used for the extraits of several fragrances.
Guerlain, Caron and Jean Patou fragrances are displayed at Selfridge’s beauty department.
From the far left: there are Guerlain Mitsouko (in the flacon bouchon coeur) and Vol de Nuit (in the flacon rayonnant) on a tray.
On the glass counter there are Jean Patou Colony (in the quirky pineapple bottle) and L’Heure Attendue.
Last, there’s a bottle of Caron Tabac Blond in a glass cabinet on the far left. It’s a correct choice, because this innovative creation by Ernest Daltroff was launched in 1919.
Kitty’s perfume counter is packed with Jean Patou fragrances. We can see several bottles of Joy and three smaller bottles.

Later in the episode, a poster for Joy can be seen. 
Thanks to a larger shot, we know that those are bottles of Malabah, sitting on the glass counter next to Lily of the Valley and a factice bottle of English Fern.
Bottles of Lavandula and Orange Blossom can be seen, too.
