Lesson 3 of 6
Sampling, sizing, quality and testing
Learning objectives
- Plan a realistic sampling timeline
- Build a sizing process that protects against returns
- Set quality standards your supplier will follow
- Wear-test before you bulk-order
Samples cost less than bad stock
Plan two or three sample rounds. Round one tests the basic make. Round two tests fit and fabric in real conditions. Round three is your pre-production sign-off. Skipping rounds is the most common reason first launches lose money on returns and reprints.
Sizing is a system, not a guess
Use a clear size chart with measurements, not just S/M/L. Test on bodies that match your real customer range — not only your fittest training partner. Document every adjustment between rounds. For apparel, expect 20–30% return rates if sizing is sloppy; under 10% if it is tight.
Quality standards in writing
Agree fabric weight, stitch type, print method, tolerances and packaging with the supplier in writing. Spot-check the first 50–100 units on arrival. A simple QC checklist saves arguments later and protects your reviews.
Founder insight — Derrick Twum
Every founder I know who skipped a sample round paid for it twice — once in returns, and once in the reorder. Sampling is not a delay; it is insurance.
Key takeaway
Sample in rounds, document sizing, write down quality standards, and wear-test before bulk.
Reflection questions

- 2Who will wear-test, beyond you?
- 3What is your written quality standard?
Action task
Draft a sampling timeline with three rounds, a sizing test panel of at least six people across the size range, and a one-page QC checklist.
