An undershirt sample order is really two orders in one: the size set proves the fit across the body range, and the wash sample proves the fabric behavior after the customer’s first laundry cycle. Ordering only one piece, in one size, unwashed, is the most common reason a basics launch discovers its problems after the bulk arrives. According to Finetex’s published undershirts program details, its line covers crew neck, V-neck, tank, and long-sleeve styles with OEM and ODM support, which gives a buyer a clear reference for what a complete sample program should cover. This guide walks the two-sample strategy from the order form to the approval record.
Sample Types for a Basics Line
The sample types follow the questions they answer. A fit question needs a size set, a fabric behavior question needs a wash sample, a decoration question needs a printed or labeled sample, and a production question needs a pre-production sample. A first undershirt order typically runs the first three, with the pre-production sample added before bulk.
| Sample type | Question it answers | What to order |
|---|---|---|
| Size set | Does the fit work across sizes? | One piece per size |
| Wash sample | How does the fabric behave after washing? | Two or three pieces in the main color |
| Decoration sample | Do the print, label, and tag look right? | One piece with the final decoration |
| Pre-production sample | Is the bulk configuration locked? | One piece from the planned production setup |
The sample plan should be written before the factory is contacted, because each sample type has its own lead time and its own approval gate. A buyer who asks for “a sample” receives the factory’s default, which may answer none of the questions that matter for an undershirt.
Ordering the Size Set
The size set is the fit evidence. Order one piece in each size the brand will sell, from the smallest to the largest, and measure every piece against the size chart the brand intends to publish. The size set is where the size chart becomes a real document rather than a copied table.
The fit check should happen on a body, not on a table. Have three to five people with different builds try the pieces, and record the fit comments per size. The neckline, the length, and the shoulder sit differently on different bodies, and a size set that only gets measured never reveals the fit problems customers will report.
The size set also answers the grading question. The difference between sizes should be consistent, so a medium that fits and an extra-large that pulls in the shoulders signals a grading problem rather than a styling decision. Record the measurement per size and check the step between sizes before approving.
Wash and Care Samples
The wash sample answers the question the size set cannot: what happens after the first wash. Order two or three pieces in the main selling color, and run them through the customer’s likely care cycle, including the detergent and the drying method. Measure the length, the width, and the seam straightness before and after the wash.
The wash check is where the undershirt’s core promise is proven. A garment worn under another layer must hold its length and its neckline through repeated washes, because a shrunk or twisted undershirt fails the moment it is worn. The wash sample should also be checked for pilling on the rubbing zones and for the behavior of the label after washing.
The wash cycle should match the care label the brand plans to print. If the care instruction says machine wash cold and tumble dry low, the test should run that exact cycle, because a gentler test than the label inflates the approval. The wash record belongs in the same file as the measurements.
The wash sample also covers the color and the surface behavior. Check the main color for fading and dye transfer in the first wash, because a white shirt worn under a colored undershirt will expose any bleeding immediately. Rub the fabric in the armpit and the collar zones after washing and compare the surface to the unwashed piece, since those are the areas customers judge by feel. The wash sample is the last place to catch a fabric behavior problem before the cost becomes a bulk problem.
What to Record at Receipt
The receipt check starts the approval record. On the day the samples arrive, photograph each piece flat and on a hanger, note the order date and the arrival date, and compare the received pieces to the order form. The arrival date becomes the lead time evidence, and the photograph becomes the standard for the bulk comparison.
The record should include the fabric weight, the fiber content, the color reference, and the label details as received, because the sample is the proof of what the factory understood. A sample that arrives with the wrong fiber content, or without the planned label, has failed before the fit check begins.
The receipt record is also the reorder asset. When the same undershirt is reordered a season later, the approval file gives the factory the exact reference, and the new samples are compared to the old record rather than to memory.
The receipt check should also confirm the sample matches the order quantity and the size labels. A size set that arrives with two mediums and no small, or with the wrong size tags sewn in, is a shipping and labeling problem that must be caught before the fit session, not during it. Note every discrepancy in the record and send it to the factory in writing, because the receipt record is the first evidence in the quality file.
Sample Fees and Timing
Sample fees and timing should be confirmed in writing before the order. According to Finetex’s published program details, sample development runs about five to seven days after the spec is approved, and the calendar should be booked backward from the launch date. The fees are usually stated per sample type, with the size set carrying a higher fee than a single piece.
The timing question is as important as the fee question. Ask for the sample calendar in the first reply, and check whether the clock starts at the spec approval or at the payment. A factory that starts the clock at the spec approval can be held to the date; a factory that starts it at an unspecified event cannot.
The buyer should also confirm what happens to the fees on a reorder. Some factories credit the sample fee against the first bulk order, and the credit terms belong in the order file before the sample is paid for, not after.
The written confirmation should also state what happens when a sample fails the check. Whether the factory revises the sample at a discounted fee, charges the full development rate again, or covers the revision depends on the agreement, and the terms are easier to negotiate before the failure than after it. Ask for the sample delivery method and the shipping cost as part of the same confirmation, because the sample is only useful when it arrives in time for the fit and wash testing window.
From Sample Approval to Bulk
The move from sample to bulk is a document transfer. The approved samples, the measurement records, the wash results, and the decoration approvals should be listed in the purchase order, with the bulk acceptance rules written beside them. The buyer who releases bulk without the record has no standard to judge the shipment against.
A product development lead’s view on basics sampling
A product development lead who manages basics sampling for online brands describes the two-sample strategy as the cheapest insurance a first order can buy. In their experience, the brands that skip the wash sample discover shrink and twist in the first customer reviews, while the brands that run it catch the problem in a week. Their standard advice is to treat the size set and the wash sample as one order, because the fit and the fabric behavior are the two things an undershirt customer actually keeps.
Finetex’s men’s undershirts manufacturing page covers the sampling and development process for private label basics, and its contact page accepts sample requests with the spec details. Bring the size range, the wash cycle, and the launch calendar, and the factory can run the samples against the dates the launch needs.
Frequently Asked Questions
How many samples should I order for an undershirt launch?
Order a size set of one piece per size plus two or three wash samples in the main color, and add a decoration sample if the brand uses print or special labels.
Why do I need a wash sample if the fit sample passes?
The fit sample measures the garment as made; the wash sample measures how the fabric behaves after the customer’s first laundry cycle, which is where shrink and twist appear.
What should I measure on the size set?
Measure the length, width, shoulder, neckline, and sleeve on every size, and check the measurement step between sizes for consistent grading.
How long does undershirt sampling take?
According to Finetex’s published program details, sample development runs about five to seven days after the spec is approved, before the bulk lead time is added.
Do sample fees count toward the bulk order?
It depends on the factory. Confirm the credit terms in writing before paying the sample fee, and record them in the order file.
What should the purchase order reference from the samples?
The approved size set, the wash results, the decoration approvals, and the receipt photographs, so the bulk acceptance is a comparison to a record rather than a memory.
