How do I find a clothing manufacturer in India?
Four routes work, roughly in this order of usefulness. Ask other brands in your category who they use and, more usefully, who they left. Walk one of the trade fairs — Bharat Tex or the India International Garment Fair in Delhi — where you can handle the sample range instead of reading a deck. Search by cluster and category rather than by the word manufacturer, because the country is regional: Tiruppur and Ludhiana for knits, Delhi and Gurgaon for woven womenswear and design-led programmes, Jaipur for hand-work, Surat for texture fabrics. Then approach the factory directly and ask for a proto rather than a quotation.
Sourcing agents and B2B marketplaces will fill your inbox fastest and teach you least. An agent is a layer between you and the floor, useful if you cannot travel and expensive in information: when bulk drifts, you hear about it a week late. Marketplace listings tell you a unit exists, not what it is good at.
Whichever route you take, the shortlist should end at two or three units and each of them should be making something for you before you commit a season to any of them.
