Mlle. Modiste is an operetta in two acts composed by Victor Herbert with a libretto by Henry Blossom. It concerns hat shop girl Fifi, who longs to be an opera singer, but who is such a good hat seller that her employer, Mme. Cecil, discourages her in her ambitions and exploits her commercial talents. Also, Fifi loves Etienne de Bouvray, who returns her love, but his uncle, Count Henri, opposes their union.
