Garment sampling is one of the most important stages between product development and bulk manufacturing. Samples allow brands, buyers, and factories to evaluate a garment before and during production and confirm that the product meets approved requirements.
A structured sampling process helps identify fit, construction, material, workmanship, and production issues at the right stage. It also creates clear approval points as the garment moves from development into bulk production and finally to shipment.
What Is the Garment Sampling Process?
The garment sampling process is a series of sample development, review, and approval stages used throughout apparel production.
Each sample has a different purpose. Early samples focus mainly on product development and fit, while later samples confirm production readiness, bulk production consistency, and the finished product before shipment.
The exact terminology and requirements can vary depending on the brand, buyer, factory, or product category, but a typical apparel production sequence includes development, fit, pre-production, top-of-production, and shipping samples.
Sample Sequence in Apparel Production
Development Sample → Fit Sample → PP Sample → Bulk Production → TOP Sample → Shipping Sample
Understanding the purpose of each stage helps brands and factories know what should be reviewed, when approval is required, and which issues need to be resolved before moving forward.
1. First or Development Sample
The first or development sample turns the initial design concept and product specifications into a physical garment.
At this stage, the product development team evaluates the overall silhouette, construction, proportions, design details, fabric behavior, trims, and whether the original concept works as intended.
The first sample often reveals issues that were difficult to identify from sketches or specifications alone. These may include construction difficulties, measurement problems, unsuitable materials, or design details that require adjustment.
More than one development sample may be required before the garment is ready to move into the fit and approval stages.

2. Fit Sample
The fit sample focuses on garment measurements, proportions, balance, comfort, and how the product fits the intended body.
Fit should be evaluated systematically rather than simply deciding whether a garment looks right.
Measurements should be checked against the specification sheet, and comments should clearly identify any changes required. Areas such as body length, chest or waist measurements, sleeve position, armhole shape, rise, inseam, garment balance, and overall silhouette may need adjustment depending on the product.
Revised fit samples may be required until the garment meets the approved fit and measurement standards.
Material and Trim Evaluation During Development
Materials should also be evaluated throughout the development and fit process.
Fabric, trims, labels, closures, thread, elastic, and other components can affect the garment’s appearance, fit, performance, cost, and manufacturability.
Whenever possible, samples should be reviewed using materials that are representative of actual production. Brands should consider fabric weight, stretch, shrinkage, construction behavior, color, availability, minimum order requirements, and compatibility with the garment design.

Sample Comments and Revisions
Clear sample comments are essential throughout the sampling process.
Comments should identify the exact measurement, construction, workmanship, material, or design change required. Vague instructions such as “improve the fit” or “make it better” can create confusion and unnecessary sampling rounds.
Photographs, measurement charts, marked samples, sketches, and written instructions can all help factories understand corrections.
Each revised sample should also be checked against the previous comments to confirm that requested changes were implemented correctly.
3. PP Sample — Pre-Production Sample
The PP sample, or Pre-Production Sample, is one of the most important approval stages before bulk production begins.
By this point, the design, fit, measurements, construction, fabrics, trims, colors, labels, and other major product requirements should be substantially finalized.
Ideally, the PP sample should be made using the actual or approved production materials and construction methods so that it represents the garment the factory intends to manufacture in bulk.
The PP sample should be reviewed for:
- Approved measurements and fit
- Fabric and trim accuracy
- Construction details
- Labels and placement
- Color and appearance
- Finishing requirements
- Overall conformity with approved specifications
Any unresolved issues should be corrected before bulk production begins.
Bulk production should normally proceed only after the required PP approval and other production requirements have been completed.
Bulk Production Begins
Once the product is approved for production, the factory begins manufacturing the bulk order according to the approved specifications, materials, samples, and workmanship standards.
Sample approval does not mean that quality monitoring stops.
The next sample stage checks whether the garments actually being produced in bulk remain consistent with the approved product.
4. TOP Sample — Top of Production Sample
The TOP sample, or Top of Production Sample, is taken from the actual production line after bulk manufacturing has started.
This is an important distinction from the development, fit, and PP samples.
A TOP sample is not simply another development sample. It represents garments being manufactured under actual bulk production conditions.
The TOP sample is reviewed to confirm consistency with approved requirements, including:
- Measurements
- Fabric and trims
- Construction
- Stitching
- Workmanship
- Labels
- Color
- Finishing
- Overall appearance
The purpose is to identify any difference between the approved PP standard and the garments coming off the production line.
If significant problems are found, corrective action should be taken quickly before the issue affects a larger portion of the production quantity.
5. Shipping Sample
The shipping sample represents finished garments at or near the completion of production and packing.
It provides a final reference for what has actually been manufactured and prepared for delivery.
Depending on the buyer or production program, a Shipping Sample may be reviewed for:
- Finished garment appearance
- Measurements and workmanship
- Labels and hangtags
- Folding and presentation
- Packaging
- Polybags or cartons
- Assortment or packing requirements
- General conformity with the approved product
The Shipping Sample can also serve as a record of the finished goods that were prepared for shipment.
Requirements and terminology may vary between brands, buyers, and factories, but the purpose is generally to provide a final product reference close to the shipment stage.
Why Each Sample Stage Matters
Each sample stage answers a different production question.
The Development Sample asks: Does the design work as a garment?
The Fit Sample asks: Does the garment fit and measure correctly?
The PP Sample asks: Is the product ready for bulk production?
The TOP Sample asks: Is actual bulk production matching what was approved?
The Shipping Sample asks: Does the finished product being prepared for delivery meet expectations?
Treating these stages as separate checkpoints helps prevent one approval from being used for a purpose it was never intended to serve.
Common Garment Sampling Problems
Sampling can become expensive and time-consuming when requirements are unclear or approvals are rushed.
Common problems include incomplete specifications, repeated design changes, incorrect materials, unclear fit comments, inconsistent measurements, unresolved construction details, poor communication, and beginning production before important issues are closed.
Another risk is assuming that an approved PP sample guarantees that all bulk garments will automatically be correct. That is one reason TOP review and ongoing production quality control remain important after manufacturing begins.
Why Garment Sampling Matters
Problems identified during development and sampling are generally easier and less expensive to correct than problems discovered after large quantities have been manufactured.
A well-managed sampling process helps brands verify product design, fit, materials, construction, workmanship, and production readiness at the appropriate stages.
It also creates clearer communication between brands, suppliers, and factories and provides approved references that can be used throughout production.
