Rhinestone Underwear Set for a Public School District in Ireland
A Public School District 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
- Unclear responsibility when a defect shows up after washing
- Inconsistent sizing between production runs
- Color drift between lab dips and bulk fabric
What we specified
| Product | Rhinestone Underwear Set |
|---|---|
| Client type | A Public School District |
| Market | Ireland |
| Order volume | 500 pieces across 4 colourways |
| Base fabric | Waffle Knit |
| Decoration | Bonding Construction |
| Size range | XS-3XL |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Waffle Knit and locked shrinkage allowance before grading.
- Decoration was moved to Bonding Construction 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
- 500 pieces delivered inside the 10-week window.
- Unit cost held within 1.5% 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
Fix the size ratio early. Changing the ratio after cutting starts is the single most expensive change a client can request.

Tell us the quantity, target price and delivery window, and we will build a customisation programme around those three numbers.
