Chambray

Chambray is a plain-weave cotton woven with a dyed warp, classically indigo, and a white weft. The one-and-one interlacing shows both yarns equally, which gives chambray its frosted, even color and a flat, smooth face. It shares its yarns with denim but not its structure: denim interlaces the same indigo warp and white weft in a twill, which is why denim shows a diagonal and a white underside while chambray looks the same on both faces.
