Bias cut means a cut made diagonally across the grain of woven fabric, commonly near a 45-degree angle.
Where you will notice it
Bias allows cloth to stretch and flow around the body without added elastic, but it can also lengthen or twist during wear.
What to examine closely
Check that hems have been allowed to settle, side seams hang straight and the garment has enough ease rather than relying on strain.
A decision worth making
When a product description mentions Bias cut, return to the garment and verify the claim. Ask what the feature changes for your body, your day and the long-term care of the piece.
