Inside Boys Swim Trunk for a Construction Firm in Belgium
A Construction Firm approached us with a inside boys swim trunk requirement for Belgium. 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
- Minimum order quantities far above what a growing brand can absorb
- Inconsistent sizing between production runs
What we specified
| Product | Inside Boys Swim Trunk |
|---|---|
| Client type | A Construction Firm |
| Market | Belgium |
| Order volume | 3,000 pieces across 6 colourways |
| Base fabric | Merino Wool |
| Decoration | Embossing |
| Size range | Custom grading |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Merino Wool and locked shrinkage allowance before grading.
- Decoration was moved to Embossing 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
Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
