Inside Boys Swim Trunk for a Shopify DTC Brand in Singapore
A Shopify DTC Brand approached us with a inside boys swim trunk requirement for Singapore. 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
- Packaging that arrives crushed and unsellable
- Minimum order quantities far above what a growing brand can absorb
- Suppliers who disappear once the deposit is paid
What we specified
| Product | Inside Boys Swim Trunk |
|---|---|
| Client type | A Shopify DTC Brand |
| Market | Singapore |
| Order volume | 500 pieces across 2 colourways |
| Base fabric | Mulberry Silk |
| Decoration | Dye-Sublimation Printing |
| Size range | Custom grading |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Mulberry Silk and locked shrinkage allowance before grading.
- Decoration was moved to Dye-Sublimation Printing 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
- 500 pieces delivered inside the 5-week window.
- Unit cost held within 1.5% of the original quotation.
- Return rate linked to fit or workmanship stayed under 0.5%.
- 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.
