Case Study: Custom Purple Girls Swimsuit for a Boutique Fitness Studio in the Netherlands
Purple Girls Swimsuit for a Boutique Fitness Studio in the Netherlands
A Boutique Fitness Studio approached us with a purple girls swimsuit requirement for the Netherlands. 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
- Color drift between lab dips and bulk fabric
- Long lead times that miss the selling season

What we specified
| Product | Purple Girls Swimsuit |
|---|---|
| Client type | A Boutique Fitness Studio |
| Market | the Netherlands |
| Order volume | 5,000 pieces across 2 colourways |
| Base fabric | Selvedge Denim |
| Decoration | All-Over Sublimation |
| Size range | Custom grading |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Selvedge Denim and locked shrinkage allowance before grading.
- Decoration was moved to All-Over Sublimation 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
- 5,000 pieces delivered inside the 8-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.
