What is "bigouden"

Bigouden (in Breton, Ar Vro Vigoudenn, pronounced ['vro vi'gudn], In French, Pays Bigouden), historically known as Cap Caval, is, along the Bay of Audierne, the most south-western area of Bro Kernev in Brittany, south-west of Quimper, defined since 1790 in the French departement of Finistère. The designation was an informal label taken from the name of the distinctive headdress traditionally worn by the local women. By the end of 19th century, the name then slipped to designate the women of the area, then to describe all its inhabitants. It has since been formalised within the administration and promotion of the region.
