Jacket Zipper Slider for an Independent Fashion Designer in Norway
An Independent Fashion Designer approached us with a jacket zipper slider requirement for Norway. 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
- Long lead times that miss the selling season
- Suppliers who disappear once the deposit is paid
- Inconsistent sizing between production runs
What we specified
| Product | Jacket Zipper Slider |
|---|---|
| Client type | An Independent Fashion Designer |
| Market | Norway |
| Order volume | 5,000 pieces across 4 colourways |
| Base fabric | Jersey Knit |
| Decoration | Pleating |
| Size range | Custom grading |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Jersey Knit 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
- 5,000 pieces delivered inside the 5-week window.
- Unit cost held within 2.0% 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
Keep one process owner on both sides. Most delays come from hand-offs, not from machines.
