Case Study: Custom Rhinestone Underwear Set for a Marathon Organizer in Denmark

Rhinestone Underwear Set for a Marathon Organizer in Denmark

A Marathon Organizer approached us with a rhinestone underwear set requirement for Denmark. 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
• Color drift between lab dips and bulk fabric

What we specified

How it was resolved

1. We rebuilt the tech pack around Cashmere and locked shrinkage allowance before grading.
2. Decoration was moved to Ribbed Cuff and Hem 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

• 500 pieces delivered inside the 10-week window.
• Unit cost held within 3.0% of the original quotation.
• Return rate linked to fit or workmanship stayed under 0.5%.
• 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.
