Understanding Bias Cut and Why It Matters
Launch library · evergreen read

Bias cutting means cutting fabric at a forty five degree angle to the grain, rather than straight along it, which fundamentally changes how the finished fabric behaves once made into a garment. This diagonal cut allows fabric to stretch slightly and cling gently to the body's natural curves, producing a fluid, almost liquid drape that a straight cut simply cannot achieve.
The technique is more demanding to work with than straight cutting, since bias cut fabric moves and shifts considerably more during construction, requiring extra care, more fabric overall, and a genuinely skilled hand to sew accurately without distorting the finished shape as it is stitched together.
Bias cut garments often need to hang for a period before hemming, since the fabric can stretch slightly under its own weight once suspended vertically for the first time. A tailor experienced with bias cutting will usually account for this extra step, producing a far more even, reliably consistent hemline as a result.
