Mainbocher is a fashion label founded by the American couturier Main Rousseau Bocher (1890-1976). The house of Mainbocher opened in Avenue George V in Paris in 1929, and in New York in 1940. Mainbocher designed expensive, elegant haute coutre dresses and gowns for an exclusive clientele that included fashion editors, socialites and stars.
In 1940, Main Bocher relocated his business to 57th Street, New York, right next to Tiffany’s. He continued to design for an elite clientele. In 1947, eight of the New York Dress Institute's Ten Best-Dressed Women in the World were Mainbocher clients. In 1961, Mainbocher moved his business to the KLM Building on Fifth Avenue. He retired in 1971, at the age of 81, and closed his fashion house.
