Designer Thong Competition Swimsuit in Tencel with Asymmetric Closure
Designer Thong Competition Swimsuit in Tencel with Asymmetric Closure
A Boutique Fitness Studio approached us to develop a designer thong competition swimsuit around a single idea: asymmetric closure, executed in tencel. The capsule was destined for Morocco 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
- The previous factory could not hold consistency across sizes
- Unit costs were too high for a boutique price point
- Decoration durability failed after two washes

How it was built
- Reference garments and moodboards were translated into a measurement spec, not just photos.
- Tencel was confirmed with lab dips and a hand-feel approval before grading.
- The thong competition swimsuit was prototyped on the fit model, then revised twice before pre-production.
- Asymmetric Closure 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
- 2,400 pieces delivered inside the 6-week window.
- Unit cost held within 3.0% of the approved quotation.
- The a Boutique Fitness Studio 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.
