Fichu

A fichu (, from the French "thrown over") is a large, square kerchief worn by women to fill in the low neckline of a bodice.

Description
It originated in the United Kingdom in the 18th century and remained popular there and in France through the 19th with many variations, as well as in the United States. The fichu was generally of linen fabric and was folded diagonally into a triangle and tied, pinned, or tucked into the bodice in front.

A fichu is sometimes used with a brooch to conceal the closure of a décolleté neckline. The fichu can thus be fastened in the front, or crossed over the chest. The cross-over fichu sometimes extended all the way to the back. Some models include a large over-the-shoulders back piece.

The fichu found in several traditional cultures resembles a poncho that covers only the shoulders and chest.
