A bonnet is a type of headwear that typically covers the head and ties under the chin. Historically, bonnets were worn by women and children, often made from fabric or straw. They served both practical purposes, such as protection from the sun, and decorative functions, enhancing the wearer's outfit. In modern times, bonnets are less common but can still be seen in specific contexts, such as historical reenactments or traditional events. They are also used for infants, providing warmth and protection. Bonnet styles vary widely, reflecting cultural and fashion trends throughout history.
