Boys' Denim Varsity Jacket for a Railway Operator in Singapore
A Railway Operator approached us with a boys' denim varsity jacket requirement for Singapore. 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
- Unclear responsibility when a defect shows up after washing
- Packaging that arrives crushed and unsellable
- Color drift between lab dips and bulk fabric
What we specified
| Product | Boys' Denim Varsity Jacket |
|---|---|
| Client type | A Railway Operator |
| Market | Singapore |
| Order volume | 800 pieces across 6 colourways |
| Base fabric | Ripstop Nylon |
| Decoration | Pleating |
| Size range | S-4XL |
| Sampling rounds | 3 |
| Delivery window | 12 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Ripstop Nylon and locked shrinkage allowance before grading.
- Decoration was moved to Pleating 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
- 800 pieces delivered inside the 12-week window.
- Unit cost held within 2.0% of the original quotation.
- Return rate linked to fit or workmanship stayed under 2.0%.
- 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.
