Jeans Sports Jacket for a Streetwear Collective in Czechia
A Streetwear Collective approached us with a jeans sports jacket requirement for Czechia. 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
- Color drift between lab dips and bulk fabric
- Inconsistent sizing between production runs
What we specified
| Product | Jeans Sports Jacket |
|---|---|
| Client type | A Streetwear Collective |
| Market | Czechia |
| Order volume | 5,000 pieces across 6 colourways |
| Base fabric | Taffeta |
| Decoration | Garment Dyeing |
| Size range | XS-3XL |
| Sampling rounds | 4 |
| Delivery window | 10 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Taffeta and locked shrinkage allowance before grading.
- Decoration was moved to Garment Dyeing 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
- 5,000 pieces delivered inside the 10-week window.
- Unit cost held within 3.0% 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
Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
