Case Study: Custom Thong Competition Swimsuit for a Marathon Organizer in Vietnam

Thong Competition Swimsuit for a Marathon Organizer in Vietnam

A Marathon Organizer approached us with a thong competition swimsuit requirement for Vietnam. 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

• Long lead times that miss the selling season
• Inconsistent sizing between production runs
• No reliable way to track a order once it enters production

What we specified

How it was resolved

1. We rebuilt the tech pack around Rayon and locked shrinkage allowance before grading.
2. Decoration was moved to Satin Printed Label after strike-off tests showed better wash durability.
3. A pre-production sample was approved and retained as the golden reference.
4. Production ran with in-line inspection and a mid-run photo report.
5. Cartons were packed to the client's own barcode and size ratio specification.

Result

• 800 pieces delivered inside the 6-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

Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
