Herringbone, also called broken twill weave, describes a distinctive V-shaped weaving pattern which is essentially a variation of a regular twill weave fabric. A twill forms a continuous diagonal rib, whereas herringbone changes its diagonal direction at regular intervals to resemble a chevron pattern. It is distinguished from a plain chevron by the break or step when changing the diagonal direction.
Herringbone is constructed into regular vertical columns across the width of the fabric creating both subtle stripe and zigzag pattern throughout. It is most commonly woven using wool, but essentially can be woven from anything, and is mostly used for suiting and outerwear.
Herringbone weave gets its name from the herring fish as it closely resembles the arrangement of its bone structure or skeleton.
