Chambray

Chambray is a plain-weave cotton that uses a colored (usually indigo) warp yarn and a white weft yarn, the same yarn-dyeing logic as denim but in a plain weave instead of a twill. That crossing of colored and white threads gives chambray its soft heathered look, lighter and flatter than denim's diagonal rib. It's often mistaken for a light denim or a chambray-look print, but true chambray gets its color from the yarn, not from surface dyeing. Garment-weight chambray typically runs 110 to 170 g/m², closer to a shirting weight than to denim.

Because it's a plain weave, chambray presses flat and doesn't build the ridged texture of a twill. It has no stretch, drapes softly, and breathes well, which makes it comfortable in warm weather. It doesn't fade at wear points the way denim does, since the weave doesn't expose the white weft in the same concentrated way, but it does soften and fade gently overall with washing.

Chambray is a standard choice for casual button-up shirts, blouses, and lightweight dresses, and it works well anywhere a soft, breathable cotton with a bit of visual texture is wanted. It's easy to sew and presses well, making it a forgiving fabric for a first shirt project. Lighter weights can show shadowing from seam allowances, so pressing seams open and finishing edges cleanly keeps the inside as tidy as the outside.
