Denim Jacket Style for a Public School District in Vietnam
A Public School District approached us with a denim jacket style requirement for Vietnam. 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
- Inconsistent sizing between production runs
- Minimum order quantities far above what a growing brand can absorb
- Packaging that arrives crushed and unsellable
What we specified
| Product | Denim Jacket Style |
|---|---|
| Client type | A Public School District |
| Market | Vietnam |
| Order volume | 3,000 pieces across 2 colourways |
| Base fabric | Ring-Spun Cotton |
| Decoration | Snow Wash |
| Size range | XS-3XL |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Ring-Spun Cotton and locked shrinkage allowance before grading.
- Decoration was moved to Snow Wash 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
- 3,000 pieces delivered inside the 8-week window.
- Unit cost held within 4.5% 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
Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
