Case Study: Custom Girls Training Bras for an Amazon Private Label Seller in South Korea
Girls Training Bras for an Amazon Private Label Seller in South Korea
An Amazon Private Label Seller approached us with a girls training bras 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
- Color drift between lab dips and bulk fabric
- Suppliers who disappear once the deposit is paid
- Minimum order quantities far above what a growing brand can absorb

What we specified
| Product | Girls Training Bras |
|---|---|
| Client type | An Amazon Private Label Seller |
| Market | South Korea |
| Order volume | 1,200 pieces across 2 colourways |
| Base fabric | Chiffon |
| Decoration | DTG Digital Printing |
| Size range | S-4XL |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Chiffon and locked shrinkage allowance before grading.
- Decoration was moved to DTG Digital 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
- 1,200 pieces delivered inside the 10-week window.
- Unit cost held within 1.5% 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
Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
