A sample is most useful when everyone knows what it represents. An early development sample may be intended to explore a silhouette, while a pre-production sample should reflect the agreed production requirements. Before you review a sweater or cardigan, confirm the sample stage and document every difference from the planned bulk garment.
1. Check the sample against the latest specification
Record the style number, sample size, color, date, and technical specification revision. Confirm the stated yarn composition, construction, trims, labels, and finishing. If a substitute yarn or button has been used, note that limitation explicitly. Approval of the shape should not accidentally become approval of a substitute material.
2. Measure consistently
Use the agreed measurement method and units. Lay the garment out as specified, avoid stretching it unless the method requires it, and record each measurement against its target and tolerance. Useful points may include chest width, body length, shoulder width, sleeve length, and neckline dimensions, depending on the style.
Photograph the position of the tape for disputed measurements. Review fit separately from flat measurements, using the intended base size and a consistent fitting approach. If the order covers multiple sizes, agree on how the size range will be checked before release.
3. Inspect appearance and workmanship
Examine the front, back, inside, seams, and trims in suitable lighting. Look for unintended holes, loose yarn ends, inconsistent stitching, distorted edges, and uneven assembly. On patterned garments, compare placement and symmetry against the approved design. On cardigans, check the alignment of the placket and whether buttons and buttonholes work comfortably.
Keep observations specific: “left sleeve is 1 cm longer than the approved target” gives the supplier a clearer action than “fit needs improvement.” Use photographs and mark the affected area.
4. Agree on performance checks
A new sample's appearance does not establish how it will behave in use. Agree on the checks needed for the intended product, such as dimensional change after care, pilling, or colorfastness. Specify the method, acceptance criteria, and responsibility for testing rather than relying on an undefined promise to “pass quality.”
For wool products, Woolmark's product specifications illustrate how a certification program uses defined requirements and test methods. Select requirements appropriate to your product and project; do not describe an uncertified garment as certified.
5. Issue one consolidated review
Collect feedback from design, buying, and quality contacts into one dated document. For each point, state the requirement, observation, requested correction, and whether a revised sample is needed. Distinguish approved details from open issues. Ask the supplier to confirm the corrections and identify any effect on materials or scheduling.
6. Keep a clear approval record
- Identify the approved sample and specification revision.
- Close outstanding material, fit, workmanship, and packaging questions.
- Keep matching reference records with the buyer and supplier.
- Confirm that later substitutions require written review.
- Agree on the inspection arrangements for the production order.
Sample approval establishes a reference for production; the bulk order still needs the agreed checks. For your next knitwear project, prepare a measurement chart and a consolidated comment sheet before starting the sample review with our team.
