Fichu

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

[2] 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.

Some models include a large over-the-shoulders back piece.

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