Selvedge Denim Fabric for a Sportswear Brand in Vietnam
A Sportswear Brand approached us with a selvedge denim fabric requirement for the Vietnam market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Reorders that quietly changed supplier and changed the hand feel
- Elastic that lost recovery after three washes
- A spec that lived in an email instead of a tech pack
What we specified
| Item | Selvedge Denim Fabric |
|---|---|
| Client type | A Sportswear Brand |
| Market | Vietnam |
| Order volume | 20,000 pieces across 2 specifications |
| Base material | Polyester |
| Standard size | 320 gsm |
| Finish | Glossy Enamel Coating |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | California Prop 65 |
How it was resolved
- We rebuilt the specification around Polyester and locked the tolerance before bulk.
- The finish was moved to Anodised Finish after strike-off tests showed better 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 ratio specification.
Result
- 20,000 pieces delivered inside the 10-week window.
- Unit cost held within 2.0% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
