The cloche hat or simply cloche ( pronunciation ) is a fitted, bell-shaped hat for women that was invented in 1908 by milliner Caroline Reboux. They were especially popular from about 1922 to 1933. Its name is derived from cloche, the French word for "bell".
During the early twentieth century, the popularity and influence of cloche hats was at its peak. Couture houses like Lanvin and Molyneux opened to join milliners in manufacturing hats that precisely matched their clothing designs. The hats even shaped hairstyles: the Eton crop – the short, slicked-down cut worn by Josephine Baker – became popular because it was ideal to showcase the hats' shape.
Cloche hats were usually made of felt so that they conformed to the head, and were typically designed to be worn low on the forehead, with the wearer's eyes only slightly below the brim. In later years, a summer cloche might be made from sisal or straw. Cloches could also be made of beads or lace for evening wear, for cocktails, dancing or even for bridal wear.
The contemporaneous Art Deco style often influenced the outline of the brim or the style of seams. While commonly worn plain, allowing the cut and shape of a well-made hat to take precedence, a cloche could be decorated with appliqués, embroidery, jeweled brooches, scarves, fans of feathers, or similar accents. By the end of the 1920s, it became fashionable to turn the brims on cloche hats upwards. This style remained prevalent until the cloche hat became obsolete around 1933 or '34.
