Swim Shorts Girls Swimsuit for a Boutique Fitness Studio in Vietnam
A Boutique Fitness Studio approached us with a swim shorts girls swimsuit requirement for Vietnam. 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
- Color drift between lab dips and bulk fabric
- Inconsistent sizing between production runs
- Long lead times that miss the selling season
What we specified
| Product | Swim Shorts Girls Swimsuit |
|---|---|
| Client type | A Boutique Fitness Studio |
| Market | Vietnam |
| Order volume | 3,000 pieces across 3 colourways |
| Base fabric | UPF 50+ Sun Fabric |
| Decoration | Shirring |
| Size range | Custom grading |
| Sampling rounds | 4 |
| Delivery window | 12 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 12-week window.
- Unit cost held within 3.0% 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
Keep one process owner on both sides. Most delays come from hand-offs, not from machines.
