Sampling Is a Process, Not a Parcel
Sampling is not “the factory mails you a garment.” It is a chain of stages — pattern, proto, lab dip, fit sample, size set, pre-production sample — and each stage has its own cycle time and its own failure points. Buyers who watch only the final garment lose control of the calendar; buyers who watch the whole process keep it.
This is written for brand owners and product developers who need a realistic sampling timeline, and who want to see what slows it down.
The Stages, In Order
Pattern and proto. The pattern comes first, then a first garment cut from fabric the factory already holds. An incomplete tech pack surfaces here first: every missing spec becomes a question, and every question costs a day.
Lab dip and color matching. For custom colors, the mill matches your color standard on real fabric and sends a swatch for your approval. Each colorway is a separate submission, and each correction is another round.
Fit sample. The sample is redone in the correct fabric and you review the fit. This is where timelines slip the most, because fit comments turn into pattern changes, and every change restarts the clock.
Size set. Once the base size is approved, the factory grades and produces the full size run. Complex grading rules or a wide size range make this stage longer.
Pre-production sample (PPS). One garment made in the bulk fabric, built exactly the way production will build it. This is your last chance to catch problems before the bulk run goes live.
Sealed sample and approval. You sign off on the PPS, and it becomes the reference standard. Production runs to it.

The Timeline, Stage by Stage
Typical ranges for cut-and-sew projects; exact days depend on your spec.
| Stage | What happens | Typical cycle | What slows it |
|---|---|---|---|
| Pattern + proto | Draft the pattern, cut the first garment | 5–10 days | Incomplete tech pack |
| Lab dip / color match | Match the color on real fabric | 5–7 days per color | Custom colors, multiple rounds |
| Fit sample | Redo in correct fabric, review fit | 7–14 days | Fit corrections, pattern changes |
| Size set | Grade and produce the full size run | 10–15 days | Complex grading, wide range |
| Pre-production sample | Sample in the bulk fabric | 7–10 days | Fabric arrival timing |
| Approval | Sign the sealed sample | 2–3 days | Back-and-forth on fit |
Added up: a simple style runs 3–4 weeks end to end; a complex one with custom fabric, print, and a wide size range takes 6–8. Schedule against the long end, not the short end.
What Actually Slows Sampling
- An incomplete tech pack. The single biggest source of delay. Every missing measurement, seam type, and trim becomes an email thread.
- Custom colors. Lab dips rarely pass in one round. Budget two rounds per color.
- Fit changes. Every fit correction means a new pattern and a new sample. Batch your comments into one round instead of five.
- Fabric lead time. Custom or imported fabric takes 3–6 weeks to arrive. Order the fabric before the pattern is finished.
- Decoration setup. Embroidery digitizing and screen setup each have their own cycle. Run them in parallel with sampling, not after the sample is done.
How to Compress the Timeline
Send a complete tech pack, approve lab dips fast, batch fit comments into a single round, and run decoration setup in parallel with sampling. The timeline is not fixed — it depends on how many questions your spec still leaves open.
A Straight Answer
Wingtu Apparel is one of many options. We do full-category custom apparel — tees, hoodies, pants, outerwear, shirts, polos, knitwear, denim, and loungewear — and we treat sampling as a staged process with the cycle times stated up front. We are not the factory that takes rigid or non-apparel projects. If your line is apparel, send your tech pack and we will send back a dated sampling schedule instead of a guess.

FAQ
Q: How long does apparel sampling take?
A: A simple style runs about 3–4 weeks from tech pack to approved sample; a complex one with custom fabric and print takes 6–8 weeks. The exact number depends on your spec.
Q: What is the difference between a proto and a fit sample?
A: The proto is the first version, often made in a substitute fabric, to show the general shape. The fit sample uses the correct fabric so you can judge the fit and the measurements.
Q: Why does a lab dip take so long?
A: Every colorway is a separate submission to the mill, and every correction is another round. Custom colors usually take two rounds. Stock colors skip this step entirely.
Q: What is a pre-production sample (PPS)?
A: A PPS is made in the bulk fabric and run exactly the way production will run it. Once you sign it, it becomes the sealed sample, and production is built to that standard.
