Spaghetti Strap Tank Top for an Amazon Private Label Seller in Mexico
An Amazon Private Label Seller approached us with a spaghetti strap tank top requirement for Mexico. 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
- No reliable way to track a order once it enters production
What we specified
| Product | Spaghetti Strap Tank Top |
|---|---|
| Client type | An Amazon Private Label Seller |
| Market | Mexico |
| Order volume | 800 pieces across 2 colourways |
| Base fabric | 3-Layer Waterproof Fabric |
| Decoration | Sequin Work |
| Size range | XS-3XL |
| Sampling rounds | 4 |
| Delivery window | 12 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around 3-Layer Waterproof Fabric and locked shrinkage allowance before grading.
- Decoration was moved to Sequin Work 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
- 800 pieces delivered inside the 12-week window.
- Unit cost held within 2.0% 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
Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
