Case Study: Custom Womens Underpants for a Marketing Agency in Portugal
Womens Underpants for a Marketing Agency in Portugal
A Marketing Agency approached us with a womens underpants requirement for Portugal. 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
- Inconsistent sizing between production runs
- Color drift between lab dips and bulk fabric
- Long lead times that miss the selling season

What we specified
| Product | Womens Underpants |
|---|---|
| Client type | A Marketing Agency |
| Market | Portugal |
| Order volume | 500 pieces across 6 colourways |
| Base fabric | Selvedge Denim |
| Decoration | Distressed Finish |
| Size range | XS-3XL |
| Sampling rounds | 3 |
| Delivery window | 8 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Selvedge Denim and locked shrinkage allowance before grading.
- Decoration was moved to Distressed Finish 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 8-week window.
- Unit cost held within 3.0% 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.
