Why Do Leggings Seams Twist?

Most likely causes

1. The fabric was cut or sewn slightly off-grain.
2. One leg panel has different tension or seam alignment.
3. Fit pressure rotates the garment as you move.
4. Laundering can exaggerate an existing construction issue.

What to try now

• Lay the leggings flat after washing and compare seam alignment before putting them on.
• Check whether the twist always returns to the same side.
• If new, document the issue before repeated wear in case the retailer treats it as a defect.

What to look for next time

• Straight seam alignment when the garment is laid flat.
• Balanced stretch on both leg panels.
• Enough room through calves and thighs to avoid rotational pull.
