Regional size names are not measurements; conversion requires a declared body or garment basis, points of measure, ease and grading rules.
Frame the decision
Map each label to finished dimensions, illustrate every measurement point and approve base and boundary sizes on physical samples.
The final chart should let pattern, inspection and packing teams identify one unambiguous size result.
Build the controlled worksheet
Keep these five topic-specific inputs together so the quotation, sample and inspection teams do not work from different assumptions:
- Body versus garment measurements: state the requirement, reference, status and approval owner.
- Measurement-point diagram: state the requirement, reference, status and approval owner.
- Fit and ease rules: state the requirement, reference, status and approval owner.
- Grade increments: state the requirement, reference, status and approval owner.
- Size-set sample approval: state the requirement, reference, status and approval owner.
Evidence to request
- Approved source or drawing for body versus garment measurements
- Order-specific record covering measurement-point diagram
- Written acceptance basis for fit and ease rules
- Controlled decision history for grade increments
- Release evidence connected to size-set sample approval
Evidence must identify the relevant product, material, revision or lot. Record any limitation, substitution or item still awaiting approval.
Risks to close before approval
- Mixing body and finished-garment measurements
- Assuming the same ease across climates or layers
- Changing labels without rechecking the size ratio
Assign an owner, due date and written disposition to each unresolved risk. Do not allow an informal answer to replace a controlled revision.
Use the result in the RFQ
Attach the worksheet, quantity, destination, required date and current sample status. Ask the supplier to list assumptions and exceptions against the same five inputs.
