What is dutch bonnet?

Dutch bonnet is a traditional headwear style for women that originated in the Netherlands in the 17th century. It is a stiff, flat-topped hat with a wide, straight brim that covers the forehead and the sides of the face. The bonnet is typically made of a sturdy fabric such as linen or wool, and is decorated with ribbons, lace, and sometimes, flowers. The Dutch bonnet was a popular style in the Western world throughout the 18th and early 19th centuries, but it fell out of fashion in the mid-19th century. Nowadays, it is mainly worn as part of traditional costumes for festivals and celebrations in the Netherlands and other parts of Northern Europe.
