Modern Jacket Zipper Slider in Cupro with Smocked Panel
A Railway Operator approached us to develop a modern jacket zipper slider around a single idea: smocked panel, executed in cupro. The capsule was destined for Peru and needed modern finishing that reads designer on the rail while staying repeatable in bulk. This case study records the brief, the specification and the delivery.
The challenge
- Decoration durability failed after two washes
- Fabric hand feel changed between production runs
- Delivery missed the collection launch window

How it was built
- Reference garments and moodboards were translated into a measurement spec, not just photos.
- Cupro was confirmed with lab dips and a hand-feel approval before grading.
- The jacket zipper slider was prototyped on the fit model, then revised twice before pre-production.
- Smocked Panel was applied in a controlled process to keep every piece consistent.
- Bulk ran with in-line inspection; a photo report was shared before shipment.
Result
- 600 pieces delivered inside the 12-week window.
- Unit cost held within 2.0% of the approved quotation.
- The a Railway Operator launched on schedule and reordered the same specification next season.
What we would repeat
Lock the colour standard before grading; every downstream approval depends on it.
