Case Study: Custom Rhinestone Underwear Set for a Mining Company in France

Rhinestone Underwear Set for a Mining Company in France

A Mining Company approached us with a rhinestone underwear set requirement for France. 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

• Color drift between lab dips and bulk fabric
• No reliable way to track a order once it enters production
• Minimum order quantities far above what a growing brand can absorb

What we specified

How it was resolved

1. We rebuilt the tech pack around Flame-Retardant Fabric and locked shrinkage allowance before grading.
2. Decoration was moved to Yarn Dyeing after strike-off tests showed better wash 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 size ratio specification.

Result

• 800 pieces delivered inside the 10-week window.
• Unit cost held within 4.5% of the original quotation.
• Return rate linked to fit or workmanship stayed under 0.5%.
• The specification is now on file, so reorders reproduce the approved sample.

What we would repeat

Fix the size ratio early. Changing the ratio after cutting starts is the single most expensive change a client can request.
