Boys Elastic Waist Jeans for a Marathon Organizer in Hong Kong
A Marathon Organizer approached us with a boys elastic waist jeans requirement for Hong Kong. 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
- No reliable way to track a order once it enters production
- Color drift between lab dips and bulk fabric
What we specified
| Product | Boys Elastic Waist Jeans |
|---|---|
| Client type | A Marathon Organizer |
| Market | Hong Kong |
| Order volume | 500 pieces across 2 colourways |
| Base fabric | Satin |
| Decoration | Ultrasonic Welding |
| Size range | S-4XL |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Satin and locked shrinkage allowance before grading.
- Decoration was moved to Ultrasonic Welding 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 10-week window.
- Unit cost held within 1.5% 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
Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
