Approving knitwear samples well is a skill that separates smooth production from costly surprises. Many buyers know sampling takes time but few know how to evaluate a sample rigorously or give feedback that actually improves the next round. This guide covers the knitwear sample approval process from a buyer's perspective.
A sample is a question the factory is asking you: "Is this right?" The quality of your answer determines the quality of your bulk.
Knitwear sampling typically runs through three stages, each with a different job:
| Sample | Purpose | What you approve |
|---|---|---|
| Proto | Look and handfeel | Overall design direction |
| Fit | Measurements | Fit and grading across sizes |
| Pre-production (PP) | Bulk standard | The exact quality bulk must match |
For timing on each, see our sampling lead time guide.

Do not judge on first impression alone. Check against your tech pack, point by point:
Vague feedback produces vague revisions. Make yours specific and structured:
The pre-production sample is the most important: it becomes the standard bulk is measured against. Approve it only when it is genuinely right, because everything ships to match it. Keep the approved PP sample as your physical reference for any later quality dispute.
A factory that communicates well during sampling, asking the right questions and flagging risks, is showing you how bulk production will go, see our vetting guide.
