Clothing Tech Packs, Sampling and Fabric Sourcing in India: A Brand Owner's Complete Playbook

Between your design idea and a finished garment hanging in your stockroom, three things have to go right: your manufacturer understands exactly what you want (tech pack), they prove they can make it (sampling), and the materials you've agreed on are actually what gets used (fabric sourcing). These three stages — tech pack, sampling, fabric — are where most first-time brand founders lose time, money, and occasionally their entire first season.

This guide is the complete operational playbook for all three. Whether you're working with an Indian manufacturer for the first time or you're an experienced brand looking to tighten your pre-production process, this is the single reference you need.

Part One: The Tech Pack — What It Is and Why It Determines Everything

Direct Answer — "What is a clothing tech pack?"

A clothing tech pack (technical package) is a complete specification document that tells a manufacturer exactly how to produce a garment. It includes flat technical sketches, a graded measurement chart, fabric and trim specifications, colour references, construction details, label placement, and packaging requirements. Without it, your manufacturer is interpreting rather than executing.

The Problem with Incomplete Tech Packs

Every unclear element of a tech pack becomes a manufacturer's decision. And a manufacturer making decisions about your design is a manufacturer guessing at your intentions. A garment with 12 unclear specifications will cost you 12 rounds of back-and-forth, 6 additional sampling iterations, and approximately 3 weeks of delays. In a seasonal business with a product launch date, those weeks matter.

What a Complete Tech Pack Contains

• Front and back flat sketch: Technical (not fashion illustration) drawings showing exact proportions, seam lines, pocket detail, closure position

• Measurement spec sheet: Every critical point of measure across your full size run (XS–XL or EU 34–44), graded in 0.5cm increments with tolerance allowances

• Fabric BOM (Bill of Materials): Fabric type, composition, weight in GSM, weave structure, finish, and either a supplier reference or a clear swatch

• Colour specification: Pantone PMS codes for all elements — body, thread, print, labels

• Construction notes: Stitch type and count per inch, seam allowances, hem construction, interfacing specification

• Surface treatment detail: For print or embroidery — artwork file (vector), placement measurements, colour codes, technique specification

• Trims list: Every button, zip, elastic, and fastening with size, material, colour, and supplier if specified

• Label spec: Brand woven label size and placement, care label content (REACH/EU or UK/US standard), hangtag attachment

• Packaging spec: Folding method, polybag size, carton quantity, packing list format

What to Do If You Can't Create a Tech Pack

Three viable options, in order of cost:

1. Hire a freelance technical designer on Upwork or Fiverr — budget £150–£500 per style. For EU-based founders, German and Dutch freelancers on these platforms often have strong fashion tech backgrounds.

2. Use tech pack software — Techpacker (cloud-based, intuitive), Audaces (common in European fashion), or even structured Google Slides templates available from fashion design communities.

3. Use your manufacturer's pre-production service — Ashanari offers tech pack development as part of our pre-production support services. We work from your sketches, reference garments, and brief to build the technical document collaboratively. This is the most efficient option for founders without technical design backgrounds.

Part Two: Garment Sampling — How It Actually Works in India

Direct Answer — "How does garment sampling work in India?"

Garment sampling in India is the process of producing one or more physical trial garments before bulk production begins. The manufacturer uses your tech pack and approved fabric to make a prototype. You evaluate this sample against your specification, request revisions if needed, and approve it only when it matches your standard. Bulk production begins only after written sample approval.

The Different Sample Types — And Which You Actually Need

How Long Does Sampling Take?

For a woven garment from a Jaipur manufacturer: 10–18 days from confirmed tech pack to sample dispatch. Add 4–7 days for international shipping to Europe, UK, Australia, or the USA. Total time from tech pack approval to sample in your hands: 14–25 days. For embroidered or block-printed garments with complex surface treatments: 18–28 days production, plus shipping.

What to Check When Your Sample Arrives

• ✓Measure every critical point against your spec sheet — don't guess, measure. Chest, waist, hip, length, sleeve, shoulder, armhole. Record deviations.

• ✓Check the fabric hand-feel and weight against your approved swatch. Run your hands over it, hold it up to light, check the weave.

• ✓Try it on a real body or a dress form close to your target customer's measurements. Flat measurement accuracy doesn't guarantee good fit.

• ✓Inspect every seam under direct light — 10 stitches per inch is your minimum for most woven garments. Check underarm seams, pocket openings, and waistband attachment.

• ✓For print or embroidery: check colour accuracy versus your Pantone reference in both natural and artificial light. Check placement measurements against the spec.

• ✓Wash the sample (following intended care instructions) and re-evaluate after washing. Does colour bleed? Does it shrink beyond specification? Does the print hold?

• ⚠Never approve a sample you're uncertain about to "save time." The uncertainty doesn't disappear in bulk production — it multiplies across every unit.

Writing Effective Revision Notes

When requesting revisions, specificity is everything. Compare:

Ineffective: "The shoulder area doesn't feel right." — the manufacturer cannot address this.

Effective: "The shoulder seam sits 1.5cm too far toward the front. Please shift the shoulder seam placement 1.5cm toward the back, and reduce shoulder width by 0.5cm on each side." — The manufacturer can execute this precisely.

Part Three: Fabric Sourcing in India — What's Available and How to Access It

Direct Answer — "What fabrics can I source from India for my clothing brand?"

India offers one of the world's most diverse fabric supply chains: GOTS-certified organic cotton, handloom cotton and linen, chanderi silk blends, viscose/rayon in multiple weights, raw silk, block-print-ready cotton voile, and hand-dyed natural fibre fabrics. Most are available through Jaipur fabric markets or sourced by your manufacturer directly from regional mills.

Jaipur's Fabric Sourcing Ecosystem

Jaipur manufacturers typically source fabric through three channels:

1. Local wholesale fabric markets (Bapu Bazaar, Johari Bazaar) — hundreds of fabric traders stocking standard and specialty textiles. Competitive pricing; immediate availability for standard fabrics. Good for: cotton voile, poplin, linen, viscose, khadi.

2. Regional mill partnerships — direct relationships with mills in Rajasthan, Gujarat, and Madhya Pradesh for specific fabric types. Better for consistent quality across seasons and organic certified fabrics. Good for: GOTS cotton, organic linen, specialist handloom.

3. Specialist artisan fabric producers — working directly with block printers, natural dyers, and handloom weavers to produce fabric that is itself the craft product. Unique to the Indian manufacturing ecosystem. Good for: hand block-printed fabric, dabu-resist fabric, natural-dyed cloth.

Requesting Fabric Swatches: What to Ask For

When requesting fabric samples from your manufacturer, always specify:

• Fabric type and composition (e.g., "100% organic cotton poplin")

• Weight in GSM (e.g., "130–150 GSM")

• Weave structure (plain, twill, satin, dobby)

• Finish requirement (washed, unwashed, mercerised, brushed)

• Colour direction (Pantone code or "natural undyed")

• Minimum number of swatches (request 3–4 options, not just one)

EU and UK Specific: Fabric Compliance Requirements

For European brands, fabrics must comply with EU REACH regulations — specifically Annex XVII restrictions on certain dyes and finishes. Request an OEKO-TEX Standard 100 test report or REACH compliance documentation from your fabric mill for any European market sale. UK brands post-Brexit should reference UK REACH requirements (mirroring EU REACH at time of writing). A reputable Indian manufacturer will have these documents readily available for their standard fabric range.
