Case Study: Custom Rhinestone Underwear Set for a Restaurant Chain in Ireland
Rhinestone Underwear Set for a Restaurant Chain in Ireland
A Restaurant Chain approached us with a rhinestone underwear set requirement for Ireland. 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
- Minimum order quantities far above what a growing brand can absorb
- No reliable way to track a order once it enters production
- Inconsistent sizing between production runs

What we specified
| Product | Rhinestone Underwear Set |
|---|---|
| Client type | A Restaurant Chain |
| Market | Ireland |
| Order volume | 1,200 pieces across 3 colourways |
| Base fabric | Down-Proof Nylon |
| Decoration | Piece Dyeing |
| Size range | S-4XL |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Down-Proof Nylon and locked shrinkage allowance before grading.
- Decoration was moved to Piece Dyeing after strike-off tests showed better wash 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 size ratio specification.

Result
- 1,200 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 1.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
