This was a tongue-in-cheek self-help book which suggested ways in which love affairs in the post-World War I era could be successfully conducted.

[3] Dorothy Parker, reviewing for The New Yorker, commented: "The Technique of the Love Affair makes, I am bitterly afraid, considerable sense.

"[4] Subsequent books included Pandora's Letter-Box (1929) and, in 1933, co-written with her sister June, a guide for society hostesses called The Pleasure of your Company.

In contrast to male fashion historians such as her friend James Laver and C. Willett Cunnington, Langley Moore favoured a hands-on object-based approach where she drew her conclusions after personally examining surviving artefacts.

In 1949, she debunked the myth of the 18-inch (46 cm) waist, which almost all Victorian women were supposed to have had, by measuring over 200 surviving dresses and bodices in collections across the country.

[6] A 1963 Guardian article about the Fashion Museum, Bath, by Alison Adburgham described how this came about: "It was Christmas 1928 and her mother-in-law produced some old dresses out of a trunk for charades.

Lady Moore was so surprised that the seemingly shapeless figure of a young woman of the nineteen-twenties could fit into an elegantly waisted Parisian gown of 1877, that she told Doris she might keep it".

But, as she described it to Adburgham: "As my scissors hovered over the rich lilac damask, I suddenly knew that I was about to do wrong and, with extraordinary effects upon my whole subsequent life, I desisted...if one is born with the sort of acquisitiveness collectors are plagued with, to have two of anything is to set up a mysterious kind of compulsion to multiply".

[7] Her collecting policy was firm: A good specimen is one which is not only in sound condition and of nice quality, but which embodies the features of its period in an entirely representative way.

[6] Fundraising began in earnest, and one of the chief triumphs of the campaign was when Christian Dior brought his couture collection and house mannequins to the Savoy Hotel in London, hosting a fashion show in aid of Langley Moore's museum fund.

[7] In 1957, Men, Women, and Clothes, the BBC's first colour series,[9] was filmed, with Langley Moore presenting examples from her collection.
