The Crespine (Crespinette or Сauls) is a detail of a medieval headdress. Initially, these are hair nets on the sides of the face. The crespine or caul was often lined with fabric and highly decorated with pearls, goldwork and gemstones.
The hair was divided into two sections at each side of the head and restrained in cauls made from either fabric or fine metal wire. These were usually held in place with a narrow fillet which may or may not have an additional crown or coronet added.
The crespine was often complemented by other headdresses or was part of them.
