The moment your sample comes back looking exactly right — the fit is clean, the construction holds, the color is what you specified — is one of the best moments in building an apparel brand. What happens next is where most emerging designers make their most costly mistakes. Getting from a perfect sample to a production run that matches it is not a single step. It's a process with real checkpoints, and skipping any one of them is expensive.

This guide walks through each stage of a first production run in the sequence they actually happen — not a simplified summary, but the real workflow. Use it as a checklist and a reference.

Stage 1: Tech Pack Finalization

Before a factory can produce your garment at scale, they need a complete technical package. The tech pack is your production bible — a detailed document that covers every measurable and specifiable aspect of the garment.

1

What a Complete Tech Pack Contains

Technical flat sketches (front, back, detail views), a full spec sheet with measurements by size, construction notes, seam allowances, stitch type and density, fabric callouts with specific fabric IDs or descriptions, trim details (zippers, buttons, labels, threads by Pantone number or specific supplier code), and grade rules for each size break.

If you hand a factory an incomplete tech pack — even one that looks thorough — they will fill in the gaps using their own judgment. That judgment may differ from yours. The tech pack is how you prevent interpretive decisions from happening without your input.

Common Pitfall

Approving a sample before the tech pack is finalized

Samples can look right even with a loose spec. When you move to production quantities, the factory scales from the tech pack, not from the sample. An inconsistency between your approved sample and your final tech pack means your production units may not match what you approved.

Stage 2: Pre-Production Sample

Once your tech pack is locked and your factory is selected, the next step is a pre-production sample — sometimes called a "PP sample" or "pre-pro." This is not the same as your development sample, even if it looks identical.

2

What the Pre-Production Sample Verifies

The PP sample is made from actual production materials — the same fabric lot, the same hardware, the same thread. It confirms that your garment can be produced correctly at scale using the real materials and the production team's hands, not just the sample room's. Always require a PP sample before greenlighting a production run.

"You're not approving how a garment can look. You're approving how it will consistently look across 200 units made by different hands, in sequence, under production conditions."

Stage 3: Fit Sessions and Approvals

If your garment is worn on the body — which is most apparel — it needs to be fit-tested on a live fit model or fit form before production approval. This is where you check that the measurements on your spec sheet translate correctly to how the garment actually drapes and fits on a real body.

How to Run a Fit Session

Use a fit model or dress form that represents your target size (typically size 8/medium for women's, size 32x32 or M for men's). Document every change with specific measurements — never "take it in a bit." Every annotation needs a number: "reduce side seam 0.5 inches from waist to hip." Return comments to factory in writing. Never approve verbally.

Expect at minimum two rounds of fit corrections on a first garment — often three. This is normal. The goal is not to rush through fit approval; it's to catch every issue before production locks in the problem at scale.

Stage 4: Fabric and Materials Ordering

Fabric ordering typically happens in parallel with the later stages of sample development, not after production approval. Fabric lead times from mills can run 4–16 weeks depending on the material, the supplier, and whether your fabric is a stock program or a custom development.

Ordering Sequence and Lead Time Management

Know your fabric lead time before you set your production start date. If you're ordering from a domestic mill, budget 3–6 weeks for stock fabrics, 8–14 weeks for custom colors or custom constructions. Overseas mills add logistics time. Order only after your tech pack is finalized, but don't wait until production approval — the timeline won't work.

Fabric testing is separate from ordering but belongs in this stage. Before your production fabric goes to cut, you should test it for shrinkage, colorfastness, and structural integrity. A 3–5% shrinkage rate means your graded patterns need adjustment. Find this out before production, not after.

Stage 5: Factory Communication During Production

Once production is underway, your job doesn't end. Good factory communication during a production run is the difference between catching a systematic problem on unit 12 and discovering it on unit 200.

5

What to Ask For at Each Stage

Request inline quality reports at three points: start-of-production (first 5–10 units off the line), mid-production (when 50% of the order is complete), and pre-shipment (100% inspection or statistical sampling, depending on your order size). Each report should include photos of measurement checks, construction details, and any deviations noted and how they were resolved.

Stage 6: Quality Inspection

Pre-shipment inspection is your last line of defense before product reaches your warehouse. For orders under 200 units, a 100% inspection is realistic and worth the cost. For larger orders, a statistical sampling approach using AQL (Acceptable Quality Level) tables is standard — AQL 2.5 is a common threshold for apparel.

6

What Inspection Covers

Measurements against spec sheet (check a minimum of 10% of units per size), construction quality (stitch integrity, seam allowances, no loose threads), color consistency (compare units against approved standard), trim placement (buttons, zippers, labels correctly positioned and functioning), and carton/packing verification (correct quantities, labels, folding method as specified).

Common Pitfall

Releasing payment before inspection results

Many factories require full payment or a large final payment before shipment. This is standard. What is not standard — and should not be accepted — is releasing payment before you've reviewed and approved inspection results. Withhold final payment (typically 20–30% of total) until your inspection is complete and you've approved shipment.

The Timeline You Should Plan For

First-time founders consistently underestimate how long a production run takes. Here's a realistic timeline for a small first run (50–150 units, 3–4 styles):

Total: 4–6 months from tech pack to warehouse. Planning for 3 months is a mistake that will cost you either a rushed production run or a missed launch date. Build the real timeline into your business plan.

A Note on Factory Relationships

Your first production run is also your first real stress test of a factory relationship. Pay attention to how they communicate when problems arise — because problems will arise. A factory that flags issues proactively and communicates clearly is worth more than a factory with slightly better pricing that goes quiet when things get complicated. The relationship matters as much as the price per unit.
