Inside Boys Swim Trunk for a Promotional Products Company in Thailand
A Promotional Products Company approached us with a inside boys swim trunk requirement for Thailand. 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
- Long lead times that miss the selling season
- Color drift between lab dips and bulk fabric
- Packaging that arrives crushed and unsellable
What we specified
| Product | Inside Boys Swim Trunk |
|---|---|
| Client type | A Promotional Products Company |
| Market | Thailand |
| Order volume | 2,000 pieces across 6 colourways |
| Base fabric | Interlock Knit |
| Decoration | Enzyme Wash |
| Size range | 2-12Y |
| Sampling rounds | 4 |
| Delivery window | 5 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Interlock Knit and locked shrinkage allowance before grading.
- Decoration was moved to Enzyme Wash 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
- 2,000 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 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.
