The sampling process typically involves 1–3 rounds: a proto or fit sample to evaluate silhouette and construction, then a pre-production sample (PPS) in the final fabric and trims for approval before bulk. Never approve a PPS you are not satisfied with — bulk production replicates the sample exactly.
The sampling stage is where most preventable production problems are caught — or missed. Understanding what is supposed to happen between your brief and your bulk order prevents the kind of surprises that are expensive to fix after goods have shipped.
Why sampling exists
A sample is a physical prototype that lets you evaluate fit, construction, fabric and finish before committing to bulk production. It is the most important quality checkpoint in the development process. Problems caught at sampling are inexpensive to fix. Problems caught after bulk production are not.
The stages of sampling
Proto sample
The first physical version of the garment — often in a substitute or available fabric rather than the final material. Used to evaluate silhouette, proportion and basic construction. Not intended to represent the final product in detail. The primary question at proto stage: is this the right shape?
Fit sample
Produced in the correct or close fabric. Used to evaluate fit across sizes, confirm construction details and make the decisions that will be locked into the pre-production sample. This is where you go through the garment systematically — seams, pocket placement, label position, hem behaviour.
From our experience: Brands that do not have a physical fit session — where someone actually wears the garment and moves in it — consistently produce more rounds of revisions than those that do. If you are not local to the production, arrange for the sample to be shipped and have it worn before providing feedback.
Pre-production sample (PPS)
The final sample before bulk production begins — produced in the exact fabric, trims and construction of the finished garment. Approving the PPS is the instruction to proceed to bulk cutting. This approval matters. Bulk production replicates the PPS.
Never approve a PPS you are not satisfied with because the timeline is tight. A delayed PPS approval is recoverable. A bulk production in the wrong fabric or with a misaligned seam finish is not.
How many rounds to expect
For a straightforward garment with a clear brief and good reference materials: one to two rounds. For a complex garment with significant construction detail or an unusual fabric: two to three rounds is not unusual and should be planned for.
From our experience: When a brand comes to us with a thorough brief and good references, we will almost always hit a satisfactory sample in two rounds. When the brief is vague and the references are absent, we can spend three rounds on things that could have been resolved before the first sample was cut.
What to check at each stage
– Measurements: check against your spec at every size, not just the sample size
– Construction: seam finishes, hem treatment, pocket placement, hardware alignment
– Fabric: hand feel, drape, colour accuracy against your reference — check in the actual end-use light conditions
– Labels and trims: placement, quality, branding accuracy
– Wash testing: always wash before approving, particularly for natural fibres
The brands that have the smoothest sampling processes are almost always the ones that gave us the most thorough brief and showed up to the fit session.
