Clothing Sample Types Explained: Proto, Fit, Pre-Production and TOP Samples (and How to Review One)
A pre-production sample is a finished garment made in your actual fabric, colour, fit and decoration, approved before bulk production starts. It is the one sample every order needs. This guide explains each sample type, which ones a small brand can skip, and gives a checklist for reviewing a sample properly.
In short
A pre-production sample is a finished garment made in your actual fabric, colour, fit and decoration, approved before bulk production starts. It is the one sample every order needs. This guide explains each sample type, which ones a small brand can skip, and gives a checklist for reviewing a sample properly.
The short answer: garment factories use several kinds of sample, but a small brand needs to care about one above all — the pre-production (PP) sample. It is a finished garment in your real fabric, colour, fit, labels and decoration, and bulk production should not start until you have approved it. Large brands also use proto, fit, size-set and top-of-production samples; for a small first order, a mockup followed by one well-reviewed pre-production sample is usually enough.
What are the different types of clothing sample?
| Sample | What it is | Purpose | Needed for a small order? |
|---|---|---|---|
| Mockup | A digital rendering of the design on the garment | Agree placement, colours and sizes of artwork | Yes — fast and usually free |
| Proto (development) sample | A first physical version, often in substitute fabric | Test whether the design works at all | Only for new or complex designs |
| Fit sample | A sample in the correct pattern, sometimes in similar fabric | Check measurements and fit on a body | Useful for a brand-new fit |
| Size-set sample | One garment in each size, or the smallest, middle and largest | Check grading between sizes | Rarely, at small volume |
| Pre-production (PP) sample | A finished garment in actual fabric, trims and decoration | Final sign-off before bulk | Yes — always |
| Top-of-production (TOP) sample | A garment taken from the bulk run | Confirm bulk matches the approved sample | Optional; photos often suffice |
| Counter sample | The factory's copy of a garment you supplied | Match an existing product | Only when copying a reference |
Short definitions of these terms are in the glossary.
Why can you not skip the pre-production sample?
Because it is the contract. Once you approve it, the PP sample is the physical standard that the bulk order is measured against: the fabric weight, the shade, the measurements, the print quality, the label positions. Without it, "the hoodies are not what I expected" is an argument about memory. With it, any difference is a fact.
It also catches the mistakes that are invisible on a screen: a logo that looked right in a mockup and is too small on a real chest, a colour that reads differently in fabric, a neckline that sits too high.
How long does sampling take, and what does it cost?
For most apparel a pre-production sample takes 7–10 days to make, plus shipping. Leather jackets and varsity jackets take about two weeks. A sample costs more than a bulk unit, because the pattern, the artwork setup and the cutting are all done for a single garment.
Two questions to ask every manufacturer:
- Is the sample cost credited against the bulk order?
- How many rounds of revision are included?
At SeamFoundry the sample cost is credited against your bulk order, and design mockups are free.
How do you review a sample? A 12-point checklist
Check the sample on the day it arrives, in daylight, before you get used to it.
- Measure it flat against the spec: chest width, body length, sleeve length, shoulder, hem. Write the numbers down.
- Try it on the body type you are designing for, and photograph front, side and back.
- Fabric weight and feel — does it match the GSM you ordered?
- Colour — compare against your reference in daylight, not under warm indoor light.
- Stitching — straight, even, no skipped stitches or loose threads; seams lie flat.
- Symmetry — pockets, sleeves, hood and hem are level and matched left to right.
- Decoration — position, size, colour, sharpness and feel of every print and embroidery.
- Labels — spelling, fibre content, position and stitching. See label requirements.
- Trims — zips run smoothly, drawcords and eyelets are secure, ribbing recovers when stretched.
- Inside — turn it inside out; the inside shows the real standard of the sewing.
- Wash test — wash and dry it once the way a customer would, then re-measure and re-check the print.
- Packaging, if it is part of the order.
How should you give feedback?
- Be specific and measurable. "Reduce body length by 3 cm" works; "a bit shorter" does not.
- Mark up photos. An arrow on a picture avoids misunderstanding across languages.
- Send everything in one message. A single numbered list is acted on more reliably than ten messages over three days.
- Separate changes from approvals. Say clearly what is approved as it is.
- Confirm in writing whether a second sample is needed or whether photos of the corrections are enough.
Approved, approved with comments, or rejected?
| Decision | When to use it | What happens next |
|---|---|---|
| Approved | The sample is right | Bulk production starts |
| Approved with comments | Small, clear corrections such as moving a label 1 cm | Bulk starts with the changes; ask for photos of the first pieces |
| Rejected — resample | Fit, fabric or decoration is materially wrong | A new sample is made before bulk |
"Approved with comments" saves a week, but only use it for changes that cannot be misread.
Can you approve from photos and video instead?
Yes, when time matters, and for reorders of a style you have already handled. Detailed photos and video show construction and decoration well. They cannot show hand-feel, true colour or fit on a body, so for a first order of a new style a physical sample is worth the extra days.
Sampling with SeamFoundry
Every order includes a pre-production sample made to your spec and shipped to you, or shared by detailed photos and video if you prefer. Production starts only when you sign it off, and the pattern is kept on file so reorders match. A tech pack helps but is not required — a sketch and reference photos are enough to start. Request a quote to begin, or read how it works for the full process.
