Inside Boys Swim Trunk for a Boutique Fitness Studio in Portugal
A Boutique Fitness Studio approached us with a inside boys swim trunk requirement for Portugal. 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
- Color drift between lab dips and bulk fabric
What we specified
| Product | Inside Boys Swim Trunk |
|---|---|
| Client type | A Boutique Fitness Studio |
| Market | Portugal |
| Order volume | 1,200 pieces across 4 colourways |
| Base fabric | Genuine Leather |
| Decoration | Ultrasonic Welding |
| Size range | 2-12Y |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Genuine Leather and locked shrinkage allowance before grading.
- Decoration was moved to Ultrasonic Welding 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 8-week window.
- Unit cost held within 4.5% 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
Keep one process owner on both sides. Most delays come from hand-offs, not from machines.
