Fichu

A fichu is a large, square kerchief worn by women to fill in the low neckline of a bodice. 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.
