Lace Underpants for a Railway Operator in New Zealand
A Railway Operator approached us with a lace underpants requirement for New Zealand. 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
- Packaging that arrives crushed and unsellable
- Suppliers who disappear once the deposit is paid
What we specified
| Product | Lace Underpants |
|---|---|
| Client type | A Railway Operator |
| Market | New Zealand |
| Order volume | 800 pieces across 6 colourways |
| Base fabric | Faux Leather PU |
| Decoration | Heat Transfer Printing |
| Size range | 2-12Y |
| Sampling rounds | 4 |
| Delivery window | 12 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Faux Leather PU and locked shrinkage allowance before grading.
- Decoration was moved to Heat Transfer Printing 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
- 800 pieces delivered inside the 12-week window.
- Unit cost held within 2.0% of the original quotation.
- Return rate linked to fit or workmanship stayed under 1.0%.
- 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.
