Þjóðbúningurinn is the collective native term for the Icelandic national costumes. The national costume has enjoyed various levels of popularity since the term was coined in Iceland in the 19th century, during the fight for independence. Since 2001 the national costume is regulated by Þjóðbúningaráð (The National Costume Authority), which preserves the correct techniques of making them and instructs people.

The five following types of costume are all recognized as Icelandic National costumes. However both the kyrtill and skautbúningur were designed in the 18th century from scratch as ceremonial costumes, while the faldbúningur, peysuföt and the upphlutur are traditional daily wear of Icelandic women in olden times.

The Faldbúningur is an older type of costume worn by women since at least the 17th century and well into the 19th. In its most recognized form it incorporated a hat decorated with a curved sheet-like ornament protruding into the air and exists in two variants. One of which is the krókfaldur and the other is the spaðafaldur. Previously a large hat decorated with gold-wire bands was worn with it, as well as ruff which is the reason for the faldbúningur's wide collar, which was designed to support it. Later, around the turn of the 18th century women started to wear the much simpler tail-cap with it.
