How Clothing Sampling Works (and Why You Should Never Skip It)

Sampling works as a loop of make, review and correct, and bulk only starts once you sign off a pre-production sample. The first garment is usually a proto or fit sample, often made in an available fabric rather than your final one, so you judge the fit, not the hand-feel; its job is to be wrong in useful ways. You review it, send written changes, and typically go one or two fit rounds. Separately, a lab dip or fabric swatch confirms colour before the full garment, and you should approve it under consistent light. The pre-production sample then brings your real fabric, trims and labels together, made the way bulk will be made, and that is the approval that matters. Once signed, it becomes the sealed sample, retained by both sides as the reference for bulk. We send photos at every stage and never move to bulk without your approval. Treat the fit sample as a conversation and the PP sample as a contract.

One to three weeks per round is typical, plus shipping time to reach you, which brands often forget to count. Fabric availability is the main variable: a stock fabric in a standard colour moves quickly, while custom development or bespoke dyeing must be produced and lab-dipped before a sample can be cut at all, sometimes adding several weeks before anything is sewn. Budget for two or three rounds rather than one. The number of rounds is the part you can most influence: a complete tech pack with measurements, and feedback written against it with photographs of the garment, means each revision fixes something specific instead of an impression. A first sample that needs no changes is unusual enough that it is worth checking whether it was reviewed carefully. The practical advice is to wear and wash the sample rather than only trying it on, because fit after laundering is what your customer will actually experience.

A clothing sample is priced per style and costs far more per piece than bulk, because a single garment is cut and sewn individually rather than run through a line. Expect additional charges for each revision round, since each is effectively a new garment. Some factories credit sampling costs against a subsequent bulk order; ask, because policies vary and it is rarely volunteered. At Collective Studio, samples are charged at a fixed price, separately from bulk, and that price is confirmed in your quote before you commit. The simplest way to keep the bill down is fewer rounds, and a complete tech pack makes the first sample more accurate. Sampling is the cheapest insurance available on a production run. A fit or fabric problem caught on one sample costs the price of that sample. The same problem discovered after 500 units are finished costs the run, the lead time, and the launch date.

Check five things: fit, fabric, construction, colour and branding, and test them rather than only trying the sample on. Judge fit on a real body in the size you sampled; sampling a couple of extra sizes also shows whether the grading holds. For fabric, assess weight, hand-feel and stretch after washing it the way your customer will, because knitted cotton moves after the first wash. Measure the garment before and after against your tech pack and record both, so shrinkage becomes a specification rather than a complaint. Turn it inside out to check seams, stitching and finishing. Wear it properly to find seams that chafe or a neckline that gapes. Look at colour under consistent light against your reference or Pantone, and confirm labels, tags and prints sit where the tech pack says. Photograph the sample beside your notes so the next round corrects something concrete. Approve bulk only against a pre-production sample in your real fabric, never a fit sample in a substitute.

It depends where the sample lands. In the US, a sample worth $1 or less, or marked, torn or perforated so it cannot be sold and used only to take orders, can enter free under tariff item 9811.00.60; otherwise a Bangladesh-made sample pays the normal rate, 26.5% for a cotton T-shirt. The $800 exemption for low-value parcels is suspended for goods from every country, by courier or post, and our US import guide has the entry rules. In the UK, garments made in Bangladesh can enter duty-free under the Developing Countries Trading Scheme with proof of origin, and samples a UK business imports only to win orders, marked as samples before import, can also be relieved of import VAT. In the EU, Everything But Arms gives Bangladesh-made garments a 0% rate with proof of origin, but import VAT can still apply. Confirm the entry with your courier or broker before the sample ships.

Sometimes, but only when the fit is already known. If the style repeats a garment you have sold before, or closely copies a reference garment in the same fabric family and weight, the pattern has little left to prove, and a pre-production sample in your real fabric can do both jobs. It is a poor shortcut for a new design. A fit sample in an available fabric is quick to correct, while a pre-production sample needs your fabric in your colour first, so a fit problem found at that stage means changing the pattern after the fabric and colour are already committed. A useful test is to skip the fit round only if you would be happy to approve bulk from the very first garment you see. If you want to try it, say so in your brief, so the factory can tell you whether the pattern is settled enough to go straight to the real thing.

Measure, wash, dry and measure again at the same points. Before washing, pick three or four points of measure, such as body length, chest width and sleeve length, and record them next to the targets in your tech pack. Wash the sample the way your care label will tell customers to, dry it the same way, whether flat, on a line or in a tumble dryer, then lay it on a table without stretching it and measure again. Work out each change as a percentage: the difference divided by the original measurement, multiplied by 100. Repeat after a second and third wash, because knitted cotton can keep moving after the first. Laboratories measure it under ISO 5077, the standard method for dimensional change in washing and drying, and report it as a percentage of shrinkage or extension. A home test is not a lab report, but it shows whether the fit you approve survives real wear.

A proto sample tests whether a design can be made as drawn, while a fit sample tests the pattern and measurements in your base size on a real body. The proto is usually made in a substitute fabric of similar weight, so you judge shape, proportion and construction rather than hand feel. The fit sample is made in an available fabric, or in yours if it is ready, and you check it against the measurements in your tech pack. On a simple knit style, such as a T-shirt or hoodie, the proto and fit sample are often the same garment. Neither one is a sound basis for approving bulk, because the fabric may differ from your final choice and drape, weight and shrinkage can change. That job belongs to the pre-production sample, made in your actual fabric, colour and trims, which is then sealed. Names vary between factories, so always ask which sample you are being sent.
