Case Study: Custom Bra Underwire for a Sportswear Brand in New Zealand

Bra Underwire for a Sportswear Brand in New Zealand

A Sportswear Brand approached us with a bra underwire requirement for the New Zealand 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

• Reorders that quietly changed supplier and changed the hand feel
• A zipper puller that broke under pull test at the warehouse
• MOQ that was quoted per colourway rather than per style

What we specified

How it was resolved

1. We rebuilt the specification around Iron and locked the tolerance before bulk.
2. The finish was moved to Epoxy Doming after strike-off tests showed better durability.
3. A pre-production sample was approved and retained as the golden reference.
4. Production ran with in-line inspection and a mid-run photo report.
5. Cartons were packed to the client's own barcode and ratio specification.

Result

• 10,000 pieces delivered inside the 10-week window.
• Unit cost held within 1.5% 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

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
