The factory sends a size-spec sheet full of ± numbers — and the red flags hide in plain sight among the normal tolerances.
The hidden risk
Tolerances that are too tight are impossible to meet (and get quietly ignored), while too-loose tolerances let sizing drift through unchecked.
How to judge
Check that each measurement point has a ± value, a defined measurement method, and a reference point — then compare against industry norms for the garment type.
What the factory must provide
A tolerance table with named measurement points, ± values, and the exact measurement method — signed by the buyer before cutting.
How DONGFAN handles it
DONGFAN's pattern team sets realistic, measurable tolerances per point and locks them into the signed size spec before cutting.
Buyer checklist
- Every measurement point named
- ± tolerance per point
- Measurement method defined
- Reference point stated
- Tolerances within industry norm
- Signed before cutting
