Plus Size Arm Shaper for a Streetwear Collective in France
A Streetwear Collective approached us with a plus size arm shaper requirement for France. 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
- No reliable way to track a order once it enters production
- Packaging that arrives crushed and unsellable
What we specified
| Product | Plus Size Arm Shaper |
|---|---|
| Client type | A Streetwear Collective |
| Market | France |
| Order volume | 500 pieces across 6 colourways |
| Base fabric | Polyester |
| Decoration | Heat Transfer Printing |
| Size range | XS-3XL |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Polyester and locked shrinkage allowance before grading.
- Decoration was moved to Heat Transfer 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 8-week window.
- Unit cost held within 4.5% of the original quotation.
- Return rate linked to fit or workmanship stayed under 1.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Fix the size ratio early. Changing the ratio after cutting starts is the single most expensive change a client can request.
