Case Study: Custom Boys' Denim Varsity Jacket for an Amazon Private Label Seller in the Netherlands

Boys' Denim Varsity Jacket for an Amazon Private Label Seller in the Netherlands

An Amazon Private Label Seller approached us with a boys' denim varsity jacket requirement for the Netherlands. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive shipping and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.

The challenge

• No reliable way to track a order once it enters production
• Color drift between lab dips and bulk fabric
• Unclear responsibility when a defect shows up after washing

What we specified

How it was resolved

1. We rebuilt the tech pack around Lambswool and locked shrinkage allowance before grading.
2. Decoration was moved to Garment Dyeing after strike-off tests showed better wash durability.
3. A pre-production sample was approved and retained as the golden reference.
4. Production ran with in-line inspection and a mid-run photo report.
5. Cartons were packed to the client's own barcode and size ratio specification.

Result

• 3,000 pieces delivered inside the 5-week window.
• Unit cost held within 1.5% of the original quotation.
• Return rate linked to fit or workmanship stayed under 1.5%.
• The specification is now on file, so reorders reproduce the approved sample.

What we would repeat

Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
