Separate the causes
Allowance restraint
Compare the actual curved seam allowance with the approved construction; look for locally crowded layers.
Unequal feeding
Mark matching points on both pieces and check whether they remain matched after sewing.
Support during pressing
Compare the seam on the planned shaped support rather than assuming a flat board reproduces the garment.
Steps before deciding
- Retain the exact failed curve with grain marks.
- Compare stitching and allowance geometry before pressing.
- Record clipping or grading already performed.
- Trial one approved allowance or feeding change.
- Approve the curve on the assembled garment after care.
Worked example
Hypothetical trial: a straight seam is flat but the curved version rolls at its tightest radius. Investigate local geometry instead of declaring every seam in the lot defective.
Buyer questions
Can I clip more deeply?
Only under an approved construction trial that also checks strength and fraying.
Is a straight seam test enough?
No; it does not represent the curve’s geometry.
