Cloche

"The cloche hat or simply cloche (pronunciation (help·info)) 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".

The popularity and influence of cloche hats was at its peak during the early twentieth century. Couture houses like Lanvin and Molyneux opened ateliers 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." - (en.wikipedia.org 05.04.2022)
