She was known for her good taste, and was a fashion icon who often launched the latest fashion in high society, which was then followed by others.

Dame d'atour

When Napoleon divorced Josephine and remarried to Marie Louise, Jeanne Charlotte du Luçay was assigned to be a part of the entourage to Branua to receive Marie Louise and escort her to Napoleon in Compiègne.

When the household of Marie Louise was formed, her superior Adélaïde de La Rochefoucauld was replaced by Louise Antoinette Lannes, Duchess of Montebello, and du Luçay succeeded Émilie de Beauharnais as Dame d'atour, while the Duchesse de Bassano, Comtesses de Montmorency, Madame Mortemart, Madame de Bouille, Madame Talhouet, Madame Lauriston, Madame Duchatel, Madame Montalivert, Madame Peron, Madame Lascaris, Madame Noailles, Madame Ventimiglia, Madame Brignole, Madame Gentili, and Madame Canisy were named Dame du palais.^[1]

As Dame d'atour, she was second in rank of all the ladies-in-waiting to the empress, responsible for her wardrobe and jewels and supervising the expenses and business transactions connected to them. Because of the lack of interest of her superior, the Duchess of Montebello, she also took over her task of administrating the alms and charities of the empress. She was present during the birth of the King of Rome 20 March 1811.

Her spouse temporarily regained his court office during the Hundred Days in 1815, but after this, de couple du Luçay retired to private life.
