Bra Underwire for a Startup Apparel Label in Australia
A Startup Apparel Label approached us with a bra underwire requirement for the Australia 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
- An interlining that bubbled after the first press
- Cartons packed to the factory ratio instead of the buyer's size ratio
- Lead time quoted without the plating or dyeing sub-process
What we specified
| Item | Bra Underwire |
|---|---|
| Client type | A Startup Apparel Label |
| Market | Australia |
| Order volume | 2,000 pieces across 3 specifications |
| Base material | Acrylic |
| Standard size | 38 mm Width |
| Finish | Pearlescent Coating |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | California Prop 65 |
How it was resolved
- We rebuilt the specification around Acrylic and locked the tolerance before bulk.
- The finish was moved to Epoxy Doming 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
- 2,000 pieces delivered inside the 4-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- 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.
