Invisible Zipper Sourcing Program for Fast Fashion Retailers: Bras

Invisible Zipper Programme for Fast Fashion Retailers: Bras

This programme covers the full path from a invisible zipper requirement to a repeatable bulk supply for fast fashion retailers. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 5# Gauge, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around bras, which is where most of the specification detail sits.

The most common failure in invisible zipper sourcing is not price — it is drift. A base material changes mill, the shade moves, a plating bath changes and the item quietly stops matching the approved sample. We prevent that with a written spec, an approved counter sample and a golden sample retained at the factory.

What the programme covers

• Specification build from your tech pack or a physical reference sample
• Base material and finish options with costed alternatives
• Sampling, testing and approval against CPSIA
• Bulk production with in-line inspection and photo reporting
• Packing, documentation and shipment under the agreed Incoterm

Recommended specifications

• Copper — chosen when the item has to survive repeated laundering
• POM Plastic — used when strength and abrasion resistance come first
• Nylon — best balance of cost, availability and test performance
• Brass — chosen when the item has to survive repeated laundering

Programme parameters

Why buyers choose this route

• Plating and dyeing sub-processes planned into the quoted lead time
• Compliance documentation issued with the shipment, not after it
• Trim and fabric sourced from audited mills with test reports on file
• Written specification held on file, so every reorder reproduces the approved sample
• One accountable owner from sampling through to ex-factory

How the programme runs

1. Discovery call: quantity, target price, delivery window and compliance needs
2. Material and finish proposal with costed alternatives
3. Counter sample built from your tech pack or reference sample
4. Approval, testing and pre-production sign-off
5. Bulk production with in-line inspection and photo reporting
6. Packing, documentation and shipment under the agreed Incoterm

FAQ

Which compliance documents do you provide?

CPSIA documentation is issued with the shipment. Test reports can be ordered against any additional standard you nominate.

Can you match a physical sample?

Yes. Send the reference and we reverse engineer the specification, then produce a counter sample for approval before any bulk commitment.

Do you hold stock for reorders?

Approved specifications are kept on file and, for repeat programmes, base material can be reserved against a rolling forecast.

Can you handle our own artwork or tooling?

Yes. Artwork files or existing tooling can be used; we confirm tolerances in writing before the first production run.

Send the reference sample or tech pack and we will come back with a costed specification, a sampling timetable and the compliance documents your market requires.
