Bra Underwire for a School Uniform Buyer in Denmark
A School Uniform Buyer approached us with a bra underwire requirement for the Denmark 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
- Shrinkage that only showed up after the first wash
- MOQ that was quoted per colourway rather than per style
- Lead time quoted without the plating or dyeing sub-process
What we specified
| Item | Bra Underwire |
|---|---|
| Client type | A School Uniform Buyer |
| Market | Denmark |
| Order volume | 5,000 pieces across 3 specifications |
| Base material | Genuine Leather |
| Standard size | 6 mm Width |
| Finish | Mercerised Finish |
| Sampling rounds | 2 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | CPSIA |
How it was resolved
- We rebuilt the specification around Genuine Leather and locked the tolerance before bulk.
- The finish was moved to Antique Copper 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
- 5,000 pieces delivered inside the 8-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection 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 made from the actual bulk base material. Substitute material behaves differently in finishing.
