Apparel Production Playbook
This apparel manufacturing guide is a technical reference library for apparel development, from costing and GSM to quality control (AQL), tech packs, and export compliance. Use this apparel production playbook to understand how garments are made, what they cost, and how to reduce production risk before you place an order.
Whether you are reading a garment manufacturing guide or a clothing production guide to prepare a first collection or checking details before a bulk order, the pages below follow the order in which a production project actually unfolds. Each section opens with what it covers, and every guide inside it is written from our factory in Tirupur, where we have run production for more than 20 years.

Frequently Asked Questions
What is an apparel manufacturing guide?
A structured reference that explains how clothing is produced, from fabric and costing to quality control and shipping. As a garment manufacturing guide, this page groups our articles into six sections that follow a production project from first brief to enquiry.
How does apparel manufacturing work from start to finish?
A brand sends a tech pack and size chart, the factory quotes and makes samples, the brand approves one, bulk production follows with in-line and final inspections, and the order is packed and shipped with the right export documents.
What do I need before I contact a clothing manufacturer?
A tech pack or clear sketches, a measurement chart, fabric and trim preferences, a target quantity, and a delivery date. The guides in section D explain each item, so treat this clothing production guide as the checklist before any enquiry.
How do I estimate the cost of a garment?
Add fabric cost (consumption times price), cut-and-make or full package charges, trims, finishing, and freight. The guides in section C walk through each step with worked examples.
What does AQL mean in garment manufacturing?
Acceptable quality level: a sampling standard that sets how many defects an inspector may find in a random sample before a batch fails. Section D explains how it is applied.
