Plus Size Arm Shaper for a Kidswear Subscription Box in South Korea
A Kidswear Subscription Box approached us with a plus size arm shaper requirement for South Korea. 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
- Suppliers who disappear once the deposit is paid
- Packaging that arrives crushed and unsellable
What we specified
| Product | Plus Size Arm Shaper |
|---|---|
| Client type | A Kidswear Subscription Box |
| Market | South Korea |
| Order volume | 1,200 pieces across 2 colourways |
| Base fabric | Neoprene |
| Decoration | Custom Zip Puller |
| Size range | S-4XL |
| Sampling rounds | 2 |
| Delivery window | 6 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Neoprene and locked shrinkage allowance before grading.
- Decoration was moved to Custom Zip Puller 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 6-week window.
- Unit cost held within 4.5% of the original quotation.
- Return rate linked to fit or workmanship stayed under 1.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Lock the colour standard before grading. Once a shade moves, every downstream approval has to be redone and the calendar slips.
