FROM TECH PACK TO PRODUCTION: A BRAND’S GUIDE TO CUSTOM CLOTHING MANUFACTURING PROCESS

If you’re starting a clothing brand or scaling one, understanding the clothing manufacturing process is critical. Every step from sketching to shipment matters—not just for quality but for timelines, costs, and your brand’s reputation in the market.

This guide walks you through the essential garment production steps, with practical tips and benchmarks.

1. Concept and Design

Every product starts with an idea. Here, brands define who they’re designing for, the season, and the overall style direction.

• Create mood boards and sketches to visualize the line
• Decide on fabrics, trims, and color palette
• Build a tech pack: flat sketches, size specs, fabric details, trims, labeling, packaging, and construction notes

A detailed tech pack is your blueprint. It reduces costly mistakes later.

2. Sampling and Prototyping

This phase turns drawings into test garments. Samples show whether your design works in real life and highlight problems early.

• Prototype creation: Factories make initial samples from your tech pack
• Fit & construction checks: Adjust seams, fit, and finishing details
• Iteration cycles: Most products take 1–3 rounds; complex items may need more
• Pitfall to avoid: Vague tech packs often cause delays and rework

Sampling is where you save money, not where you cut corners.

3. Material and Trims Sourcing

Your design isn’t real until the materials are in hand. Fabric and trim sourcing is often the slowest stage of the clothing manufacturing process, and delays here can stall everything downstream. 

Many first-time founders underestimate how long it takes to secure the right textiles, especially if they’re working with specialty fabrics or custom trims.

• Source fabrics, linings, zippers, buttons, and labels
• Factor in lead times: niche or sustainable options take longer
• Secure backup suppliers where possible

Remember to source early. Your production moves only as fast as your slowest material.

4. Production Planning and Pre-Production

This phase is where preparation pays off. Once designs and materials are finalized, the factory translates everything into a roadmap for bulk production. 

Brands that rush past pre-production often regret it later — mistakes multiply quickly when you’re making hundreds of units.

• Finalize graded patterns for all sizes
• Make production markers to minimize fabric waste
• Approve a pre-production sample to confirm accuracy before scaling

Skipping pre-production checks risks hundreds of faulty units.

5. Bulk Production

This is where scale kicks in and hundreds (or thousands) of garments take shape.

Efficiency matters here, but so does consistency. A single error repeated across an entire run can lead to expensive recalls or wasted stock. That’s why strong quality control at this stage is non-negotiable.

• Fabrics cut into panels following markers
• Assembly through specialized sewing operators
• Pressing, attaching trims, washing, and finishing
• Quality control checks at multiple points

Continuous QC beats end-stage inspections — catch problems early.

6. Lead Times and Costs

For new brands, timelines and costs are the biggest shocks in the clothing manufacturing process. Even with a simple design, there are multiple moving parts — and each one adds days or weeks. 

• Design & tech pack: 1–7 days if your sketches and details are ready. Clear documentation speeds everything up.
• Fabric sourcing: 3–10 days for in-stock fabrics; longer if you need sustainable or custom-dyed options.
• Sampling & revisions: 7–14 days per round. Most brands need at least 1–2 cycles before approval.
• Bulk production: 15–30 days depending on garment complexity and order size. A basic T-shirt moves faster than a multi-panel jacket.
• Branding & packaging: 3–5 days for labels, hang tags, and polybags once designs are approved.
• Quality control: 2–4 days for orders under 2,000 units. Larger runs take longer.
• Shipping: 5–7 days by express courier, 7–10 days by air freight, and 20–45 days by sea.
