In Spain and Mexico, a peineta is a large decorative comb usually worn under a mantilla, or lace head covering. The hair ornament, worn by women, consists of a convex body and a set of teeth that affix it to hair worn in a bun. The peineta was once made of tortoise shell, but is now usually made of synthetic materials such as acrylic or plastic. The peineta is usually worn with a mantilla, a veil worn over the head and shoulders. The mantilla is also a common element of some Valencian and Andalusian costumes.
