In everyday medieval life, the bonnet primarily served practical functions: it protected the hair from dirt and dust during housework and fieldwork, provided warmth in winter, and served as a symbol of status and modesty, as married women often wore their hair covered. Today, it is used as an essential accessory at events such as LARP, reenactment, or medieval markets to complete costumes, round off the authentic look of a historical figure or fantasy character, and discreetly conceal modern hairstyles. Furthermore, it often serves as a protective undercap (bonnet) worn beneath a helmet or chainmail coif when portraying warriors.
