Case Study: Custom Thong Competition Swimsuit for a Surf School in the United States
Thong Competition Swimsuit for a Surf School in the United States
A Surf School approached us with a thong competition swimsuit requirement for the United States. 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
- Packaging that arrives crushed and unsellable
- Minimum order quantities far above what a growing brand can absorb
- Long lead times that miss the selling season

What we specified
| Product | Thong Competition Swimsuit |
|---|---|
| Client type | A Surf School |
| Market | the United States |
| Order volume | 3,000 pieces across 4 colourways |
| Base fabric | UPF 50+ Sun Fabric |
| Decoration | Shirring |
| Size range | 2-12Y |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around UPF 50+ Sun Fabric and locked shrinkage allowance before grading.
- Decoration was moved to Shirring 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
- 3,000 pieces delivered inside the 5-week window.
- Unit cost held within 2.0% of the original quotation.
- Return rate linked to fit or workmanship stayed under 2.0%.
- 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.
