Quick Guide To Sampling Process for Clothing Product Development

We can classify sampling process for a clothing line into two categories:

Development Sampling Stage

  • Prototype or Proto Sample

  • Salesman sample/photo shoot sample

  • Fit sample

  • Pre-Production Sample

Production Sampling Stage

  • TOP-top of production sample

  • Size set or size run

  • Shipment sample

 

Prototype Sample/Proto Sample

-Sample maker or factory makes Proto Sample based on sketch, specs and construction details from the technical package.

-This is the first sample in a product development stage. It is customary to submit sew by sample along with a tech pack as a guidance for a fit and construction.

 

Salesman Sample

-Salesman Sample is created in size small in the actual fabrics, trims and colors for the showroom or trade show display.

-The main purpose of the salesman sample is marketing, sales and gathering the feedback from buyers to forecast demand for a specific style.

 

Fit Sample

-The factory makes Fit Sample in the actual fabrics and trims using the specs for the base size (e.g. medium).

-Technical Designer will organize fit session to try on sample on a live model and check a fit and style details accuracy. 

-Technical Designer will measure fit sample, conduct fit session, pin the garment and send revised specs to the factory to make a new fit sample.

-Factory will review all notes and revise pattern, make a new fit sample and send it back for approval.

 

Pre-Production Sample/PP Sample

-Pre-Production or PP Sample is the name for a approved Fit Sample before bulk production start. It means that PP sample will serve as a reference in workmanship, specs and fabrication (fabrics and trims) that factory needs to follow for bulk production.

-PP Sample is an important and the last part of the development process. PP Sample is a visual and tangible agreement between the brand and the factory about how the final clothing style shipment should look and fit.

 

Top of Production Sample/TOP Sample

-During the bulk production, the factory will randomly pull a few finished garments out of a production line and send it to a buyer’s technical team for a QC (quality control).

-TOP Sample will serve as a checkpoint assurance that factory is following PP Sample specifications.

 

Size Set Samples or Size Run

-When production is done, the factory will send Size Set or Size Run (one sample of each size). This step checks the garment measurements accuracy for all sizes.

-Technical Designer records all measurements in the tech pack for the future reference.

-Ideally, size set should be sent before the start of production for the grade rule check and its proportional transfer into the graded pattern.

-Unfortunately, there is never enough time for this step.  The factory usually sends size set after they complete the bulk production.

 

Shipment Sample

-After the bulk production completion, including packing and labeling for shipment, the factory pulls a few shipment ready pieces and sends it to the customer/buyer for a reference.

-Shipment Sample will serve as a future reference for both factory and the buyer (labeling, folding, packaging, tagging etc.)

 

Conclusion

-Sampling process can be lengthy and costly and will have to be well organized and managed if you want to prevent unnecessary money spending.

-Sampling with domestic manufacturers differs from sampling with overseas factories and the order and a quantity of fit samples may vary.

-The sampling process can shape differently and will depend on the size of the clothing company and the factory they are using to produce their clothing line.

-3D Virtual Prototyping is taking an important role in changing the way we do the sampling process.

- 3D sampling technology offers the new and more efficient way to develop and manufacture the clothing line.
