Case Study: Custom Crochet Cardigan Sweater For Women for a Railway Operator in Vietnam

Crochet Cardigan Sweater For Women for a Railway Operator in Vietnam

A Railway Operator approached us with a crochet cardigan sweater for women 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

• Inconsistent sizing between production runs
• Suppliers who disappear once the deposit is paid
• Color drift between lab dips and bulk fabric

What we specified

How it was resolved

1. We rebuilt the tech pack around Down-Proof Nylon and locked shrinkage allowance before grading.
2. Decoration was moved to Flocking 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

• 1,200 pieces delivered inside the 8-week window.
• Unit cost held within 2.0% of the original quotation.
• Return rate linked to fit or workmanship stayed under 2.0%.
• The specification is now on file, so reorders reproduce the approved sample.

What we would repeat

Keep one process owner on both sides. Most delays come from hand-offs, not from machines.
