Toulouse-Lautrec, Le Divan Japonais
This Toulouse-Lautrec poster depicts Jane Avril and Edward Dujardin in "Gay 90s" Paris. Avril is wearing a hat similar to those designed by famous Parisian milliner Madame Virot. Virot collaborated with well-known courtiers of the day; the December 17, 1892 cover of Harper's Bazar Magazine shows a lady wearing a Virot hat. Virot is even mentioned in Edith Warton novels. Note also the importance of Dujardin's topper as the crucial element in his sartorial statement.
Ladies formal hats and Mens Top Hats, similar to the hats pictured here can be seen at
