Bra Underwire for a Yacht Interior Studio in Portugal
A Yacht Interior Studio approached us with a bra underwire requirement for the Portugal 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
- A zipper puller that broke under pull test at the warehouse
- Shade drift between the approved lab dip and the bulk lot
- Elastic that lost recovery after three washes
What we specified
| Item | Bra Underwire |
|---|---|
| Client type | A Yacht Interior Studio |
| Market | Portugal |
| Order volume | 10,000 pieces across 6 specifications |
| Base material | Cotton |
| Standard size | 12 mm Width |
| Finish | Matte Black Coating |
| Sampling rounds | 3 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | ISO 14001 |
How it was resolved
- We rebuilt the specification around Cotton and locked the tolerance before bulk.
- The finish was moved to Black Nickel 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
- 10,000 pieces delivered inside the 4-week window.
- Unit cost held within 3.0% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
