Tailored Inside Boys Swim Trunk in Crochet with Waist Tie Belt
A Promotional Products Company approached us to develop a tailored inside boys swim trunk around a single idea: waist tie belt, executed in crochet. The capsule was destined for Czechia and needed tailored 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
- Fabric hand feel changed between production runs
- Decoration durability failed after two washes
- Delivery missed the collection launch window

How it was built
- Reference garments and moodboards were translated into a measurement spec, not just photos.
- Crochet was confirmed with lab dips and a hand-feel approval before grading.
- The inside boys swim trunk was prototyped on the fit model, then revised twice before pre-production.
- Waist Tie Belt 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 6-week window.
- Unit cost held within 1.5% of the approved quotation.
- The a Promotional Products Company launched on schedule and reordered the same specification next season.
What we would repeat
Approve the hand feel on the actual bulk fabric — proto cloth always behaves differently.
