Caul (headgear)

Ukrainian Caul and kerchief

A caul is a historical headress worn by women that covers tied-up hair. A fancy caul could be made of satin, velvet, fine silk or brocade, although a simple caul would commonly be made of white linen or cotton. The caul could be covered by a crespine or a mesh net to secure it from falling off. It is also the name of an Elizabethan hair net.
