02Opening

This page explains the main sample types a garment order passes through, from the first rough proto sample to the top of production sample, and what each one is actually made to prove

This page is for a merchandiser, production manager, or new entrant who needs to know which sample a factory makes at each point of an order, and what that specific sample is meant to prove before the order can move to its next stage. This is chiefly a product-flow skill: an order does not go straight from a buyer's request to bulk cutting; it passes through a fixed sequence of physical samples, each one answering a different question about the garment, before a factory is allowed to cut and sew the full quantity. Without knowing which sample proves what, a factory can submit the wrong sample at the wrong time, a buyer can approve a sample for the wrong reason, and a fit problem or a fabric problem that a proto sample or a fit sample was built to catch can instead surface much later, once thousands of pieces are already cut.

03Before you start

You need: no previous lesson; this is the first lesson of Course T11-C02.

By the end of this lesson you can:

  • name the main sample types a garment order passes through, in their usual order;
  • state what each sample type is specifically made to prove;
  • identify which sample type answers a design question, which answers a fit question, and which answers a bulk-readiness question;
  • explain why a pre-production sample and a top of production sample serve different purposes even though both use bulk fabric;
  • recognise when a sample type can be skipped and when it cannot.

Not covered here: how a buyer actually reviews a submitted sample and what outcomes a buyer can issue (Lesson 2), what happens when a sample is rejected (Lesson 3), and how to turn a sample's written comments into a revision plan (Lesson 4).

04Key terms

Words you will meet in this lesson

TermMeaning
Proto sampleThe first, rough sample made from the tech pack, often in the wrong fabric, to prove the design and construction idea works before investing further.
Fit sampleA sample made in the correct fabric at the sample size, checked against the size specification to prove the garment fits.
Sales sampleA sample shown to the buyer's own customers or sales team, sometimes before the order is fully confirmed, to gauge interest; also called a salesman's sample or a counter sample.
Pre-production (PP) sampleA sample made from the actual bulk fabric and trims, the last sample checked before bulk cutting begins.
Top of production (TOP) sampleA sample pulled from the very first pieces actually cut and sewn in bulk, to prove the bulk production run itself matches the approved PP sample.
Sample sizeThe one size, usually M, that samples are made in and measured against, rather than every size in the order.
05Teaching
The rule

A garment order passes through a fixed sequence of sample types, and each one proves one specific thing the sample before it did not

A garment order is never trusted to bulk cutting on the strength of a drawing or a tech pack alone. It passes through a sequence of physical samples: a proto sample, a fit sample, sometimes a sales sample, a pre-production (PP) sample, and a top of production (TOP) sample. Each sample type exists to prove one specific thing that the sample before it could not prove, using materials and methods appropriate to the question being asked. A proto sample, often stitched in a substitute fabric, proves the design and construction idea works at all; it says nothing about fit in the real fabric, and nothing about how the real bulk fabric behaves. Skipping a sample type does not skip the question it answers; it only means that question goes unanswered until a later, more expensive stage reveals whether the answer was actually yes.

One sample type = one specific question answeredProto(design idea)Fit(real fit)Sales(buyer interest)PP(bulk-ready)TOP(bulk actually matches)
A garment order's five main sample types, in order, each proving one specific thing the one before it did not.* Skipping a sample type does not skip the question it was built to answer.
What you meet in real life

The same five sample types apply to every order, but which ones are used, and how many rounds each takes, differs by order shape and by how close a repeat order is to a proven style

What can differThe shapes you meetWhy it matters
New style vs. a repeat of an already-proven styleA brand-new style usually needs all five sample types; a repeat order close to an already-approved style can sometimes skip the proto sample and start at fit.Skipping the proto sample on a genuinely new style, rather than a proven repeat, risks discovering a construction problem only once bulk fabric has already been cut.
Export MTO order vs. domestic MTS orderNorthline Apparel, an export buyer, requires a full proto-to-TOP sequence in writing before releasing payment stages; a domestic Make to Stock brand may run a shorter sequence, since it carries the stock risk itself and can adjust the next production run instead.Treating a domestic MTS brand's shorter sequence as if it were an export buyer's own requirement risks a factory skipping a step an export letter of credit actually requires.
A sales sample used vs. not usedA sales sample is common where a buyer's own sales team or retail customers need to see the style before the order is fully confirmed; an already-confirmed reorder usually has no sales sample at all.Confusing a sales sample, made to gauge interest, with a fit sample, made to prove fit, risks treating buyer interest as if it were also a fit approval.
A hybrid line running an export order and a domestic run togetherDelta Garments' hybrid line can be running Order A's full proto-to-TOP sequence for Northline Apparel at the same time as a domestic brand's shorter sequence, on the same floor.Mixing which sequence applies to which order risks submitting a domestic-style shortcut sample as if it satisfied an export buyer's own full requirement.
Socks, terry, and home-textile product familiesA hosiery, terry, or bedding order still passes through the same named sample types, though a proto sample for socks or towels is a first knitted or woven piece rather than a first cut-and-sewn garment.The sequence's structure does not change by product family; only the physical form the sample takes changes.
The case we follow

Delta Garments takes Order A through all five sample types before Northline Apparel allows bulk cutting to begin

Delta Garments is making Order A, 15,000 basic cotton T-shirts for Northline Apparel, a new style this season. Mona, the merchandiser, first submits a proto sample stitched in a substitute fabric, since Order A's own dyed and finished fabric is not ready yet; this proves the construction, the neck rib, and the overall look match the tech pack's intent. Once Northline approves the proto sample's design, Mona submits a fit sample in Order A's actual single jersey 180 GSM fabric at size M, Order A's own sample size, measured against the tech pack's size specification. Northline also asks for a small sales sample run to show its own retail buyers ahead of full confirmation. Once the bulk fabric arrives from Colorline Dyeing, Mona submits a pre-production sample made from that actual bulk fabric and Order A's real trims. Only once Northline approves the PP sample does Karim, the production manager, release bulk cutting; once the first pieces are actually cut and sewn, Mona pulls a top of production sample from that first bulk output and submits it to prove the real production run matches what the PP sample already promised.

The worked number

Order A's five sample types sit inside a 2-week approvals window out of the order's 16-week total timeline

Order A's total timeline: 16 weeks (approvals 2 + fabric 5 + sewing 2 + inspection/packing/documents 1 + shipping 4 + warehouse/distribution 2)
Sample types inside the 2-week approvals window: proto sample, fit sample, sales sample (illustrative round)
Sample types checked later, inside the fabric and sewing weeks: pre-production sample (once bulk fabric arrives, before cutting), top of production sample (once bulk cutting and sewing has started)
Total sample types across the whole order: 5 sample types, only 3 of which fall inside the fixed 2-week approvals window

Only three of Order A's five sample types, the proto, the fit, and the sales sample, sit inside the order's own fixed 2-week approvals window at the start of the timeline; the PP sample and the TOP sample are checked later, once bulk fabric has actually arrived and bulk cutting has actually started, because neither one can exist any earlier than that.

The method

A four-step method for knowing which sample type is needed at any point in an order

1. Check whatstage the orderhas reached2. Name the onequestion that stage'ssample must answer3. Confirm theright fabric is usedfor that question4. Confirmapproval beforenext stage starts
Identifying which sample type an order needs at any point is a fixed four-step method.* Skipping step 3, using the wrong fabric for the question being asked, is how a fit sample stitched in a substitute fabric gets mistaken for proof of real fit.
  1. Check what stage the order has reached: whether the design is still unproven, the fit is still unproven, bulk fabric has arrived, or bulk cutting has actually started.
  2. Name the one question that stage's sample must answer: design idea, real fit, buyer interest, bulk readiness, or bulk-match.
  3. Confirm the right fabric is used for that specific question, since a design question can use a substitute fabric but a fit or bulk-readiness question cannot.
  4. Confirm approval is recorded before the next stage, cutting or shipping, is allowed to start.
The trap

A common mistake is treating an approved proto sample as if it also proves the garment fits

A common mistake is treating a proto sample's approval as if it also settles the fit question, because the buyer has already said the style "looks right." A proto sample is often stitched in a substitute fabric and is not measured against the size specification with the same rigour a fit sample requires; a proto sample approval proves the design idea, nothing more. Cutting bulk fabric on the strength of a proto sample approval alone, without a fit sample in the actual fabric, risks discovering a fit problem in the real single jersey 180 GSM fabric only after fabric that could have gone into approved production has already been cut for a sample nobody checked fit on.

06In plain words

A garment order does not go straight from an idea to full production. A factory makes a series of samples first, and each one is built to answer a different question. The first, rough sample proves the design idea works. The next sample, made in the real fabric, proves the garment actually fits. Sometimes a sample goes to the buyer's own sales team or shops, to see if people want it, before the order is even fully confirmed. Once the real bulk fabric arrives, one more sample proves that fabric is ready to be cut. Once cutting and sewing on the full order has actually started, a last sample is pulled from that real output, to prove the bulk production run matches what was already approved. Skipping any one of these samples does not make its question go away; it only means the answer is not known until later, when a mistake costs much more to fix.

07Quick check
  • A garment order passes through five main sample types, in a fixed order.
  • Each sample type proves one specific thing the sample before it did not prove.
  • A proto sample proves the design idea; it does not prove fit.
  • A fit sample must use the actual fabric, since fit cannot be proven in a substitute fabric.
  • A sales sample gauges buyer interest, not fit or bulk readiness.
  • A pre-production (PP) sample is the last check before bulk cutting starts.
  • A top of production (TOP) sample proves the real bulk output matches the already-approved PP sample.
  • A repeat of an already-proven style can sometimes skip the proto sample; a genuinely new style should not.
08Workplace scenario

Northline Apparel approves Order A's proto sample and asks Delta Garments to start cutting bulk fabric immediately

Delta Garments has just received Northline Apparel's written approval of Order A's proto sample, and Karim, the production manager, is deciding what to do next.

  • The proto sample was stitched in a substitute fabric, since Order A's dyed single jersey 180 GSM fabric had not arrived yet.
  • Northline's approval email says: "The proto sample looks exactly right, please proceed."
  • Order A's fit sample, in the actual fabric at size M, has not yet been submitted or measured against the size specification.
  • Order A's bulk fabric has just arrived from Colorline Dyeing, so cutting could technically start today.

The email Karim actually has in front of him:

Northline Apparel, approval email. "The proto sample looks exactly right, please proceed."

Should Delta Garments start cutting Order A's bulk fabric now that the proto sample is approved? Decide before you open the decision.

Show decision

No. The proto sample's approval proves only that the design idea is right; it says nothing about whether the garment fits in the real fabric, since the proto sample was not made in that fabric.

The two facts that decide this are the proto sample's own substitute fabric and the rule that a fit question can only be answered by a sample made in the correct fabric. Karim should submit a fit sample in Order A's actual single jersey 180 GSM fabric at size M and hold bulk cutting until Northline separately approves that fit sample against the size specification.

09What it costs

The cost of cutting bulk fabric on a proto sample approval alone, against waiting for the fit sample's own separate approval

Order A's bulk fabric is about 3,000 kg at USD 5.60 per kg, so the full order's fabric cost is 3,000 × 5.60 = USD 16,800. If Delta Garments cuts this bulk fabric before a fit problem is caught, and the fit sample later fails because the real fabric behaves differently from the proto sample's substitute fabric, the fabric already cut for wrongly-fitting pieces cannot simply be recut into more fabric; at worst a meaningful share of that USD 16,800 fabric cost is wasted, on top of the sewing labour already spent cutting and assembling pieces that must now be scrapped or reworked. Waiting for the fit sample's own separate approval, inside Order A's fixed 2-week approvals window, costs only the normal time a fit sample round already takes, a cost already built into the order's 16-week timeline, far smaller than cutting bulk fabric twice.
