Case Study: Custom Boys' Denim Varsity Jacket for a Promotional Products Company in Japan
Boys' Denim Varsity Jacket for a Promotional Products Company in Japan
A Promotional Products Company approached us with a boys' denim varsity jacket requirement for Japan. 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
- Inconsistent sizing between production runs
- Minimum order quantities far above what a growing brand can absorb

What we specified
| Product | Boys' Denim Varsity Jacket |
|---|---|
| Client type | A Promotional Products Company |
| Market | Japan |
| Order volume | 500 pieces across 2 colourways |
| Base fabric | Viscose |
| Decoration | Foil Printing |
| Size range | S-4XL |
| Sampling rounds | 4 |
| Delivery window | 12 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Viscose and locked shrinkage allowance before grading.
- Decoration was moved to Foil Printing after strike-off tests showed better wash durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and size ratio specification.

Result
- 500 pieces delivered inside the 12-week window.
- Unit cost held within 1.5% of the original quotation.
- Return rate linked to fit or workmanship stayed under 0.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Lock the colour standard before grading. Once a shade moves, every downstream approval has to be redone and the calendar slips.
