Designer Upf Protection Modest Swimwear in Tencel with Open Back
Designer Upf Protection Modest Swimwear in Tencel with Open Back
A Kidswear Subscription Box approached us to develop a designer upf protection modest swimwear around a single idea: open back, executed in tencel. The capsule was destined for Hong Kong and needed designer 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
- Delivery missed the collection launch window
- Unit costs were too high for a boutique price point
- Decoration durability failed after two washes

How it was built

- Tencel was confirmed with lab dips and a hand-feel approval before grading.
- The upf protection modest swimwear was prototyped on the fit model, then revised twice before pre-production.
- Open Back 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
- 1,500 pieces delivered inside the 8-week window.
- Unit cost held within 2.0% of the approved quotation.
- The a Kidswear Subscription Box launched on schedule and reordered the same specification next season.
What we would repeat
Keep one process owner on both sides. Most delays come from hand-offs, not machines.
