Case Study: Custom Jacket Lining Fabric Interlining Lining for a Boutique Fitness Studio in Vietnam

Jacket Lining Fabric Interlining Lining for a Boutique Fitness Studio in Vietnam

A Boutique Fitness Studio approached us with a jacket lining fabric interlining lining 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

• Color drift between lab dips and bulk fabric
• Long lead times that miss the selling season
• Suppliers who disappear once the deposit is paid

What we specified

How it was resolved

1. We rebuilt the tech pack around Interlock Knit and locked shrinkage allowance before grading.
2. Decoration was moved to Yarn Dyeing 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

• 2,000 pieces delivered inside the 12-week window.
• Unit cost held within 1.5% of the original quotation.
• Return rate linked to fit or workmanship stayed under 1.0%.
• The specification is now on file, so reorders reproduce the approved sample.

What we would repeat

Fix the size ratio early. Changing the ratio after cutting starts is the single most expensive change a client can request.
