Buyer guide

How to evaluate a sample.

A sample is the cheapest moment to find a problem. What to check, in what order, and how to write comments a factory can act on.

In short

Evaluate a sample against your specification, not your memory of the reference: confirm it is the right sample, measure it, check construction at the stress points, judge fabric and colour under agreed light, wash it the way your program will, then write comments with a measurement or a reference for every change. Approve only what you would accept in bulk.

In this order

  1. 01

    Check it is the right sample

    Style, size, fabric and colour against what was requested. A sample in the wrong fabric cannot be approved for fit.

  2. 02

    Measure it

    Lay it flat and measure each point of measure in your size specification. Record the actual figure and the difference from specification.

  3. 03

    Check construction

    Stitch type and density, seam finish, bar-tacks at stress points, hardware attachment and label placement.

  4. 04

    Judge fabric and colour

    Weight, hand and shade under the agreed light source, against the approved lab dip or colour standard.

  5. 05

    Wear it and wash it

    Fit on a person or a form, then wash it as your program will and measure again for shrinkage and twist.

  6. 06

    Write comments that can be acted on

    One comment per point, each with a measurement, a photograph or a reference. "Make it better" cannot be sewn.

Which sample answers which question

Approving one stage does not approve the next.

Development sample
Is this the right garment? Construction and look, often not yet in the bulk fabric.
Fit sample
Does it fit? Measured and tried against the size specification.
Size set
Does the grading hold across the size range?
Pre-production sample
Is this what bulk will be? Bulk fabric, trims and construction.

Approve what you would accept in bulk

Approval makes the sample the standard the bulk is inspected against. If something is acceptable only for now, say so in writing, or it becomes the standard.

Also asked.

It depends on how complete the brief is. A full tech pack with a reference garment usually needs fewer rounds than a sketch, because fewer points are left open.

Yes. Keep the sealed sample, and have the supplier keep a counter-sample. Both sides then inspect bulk against the same garment.

PUT IT INTO PRACTICE.

Send one specification and we will apply exactly this thinking to your style. Construction, materials and commercial FOB costing.
