Think of those lovely "Ladies" which used to be called Powder Rooms, with scent bottles with those little puffer sprays, tissues in special containers, enormous mirrors, luxurious carpets and chairs and a special attendant.
Or a wonderful, very different sort of Ladies there used to be in Paddington, with a certain attendant who was always there, year after year, and who may have had a cat, I think.
These places were special havens for women.
It would be very nice if they came back, let alone nice to just keep the idea of a Ladies in the first place even if there are some gender neutral ones in addition for some people.
