How to Find a Clothing Manufacturer: The Step-by-Step Process

The manufacturer you choose shapes everything about your product — the quality, the consistency, the lead times, the cost, and ultimately, how your customers perceive your brand. A great manufacturer becomes a long-term partner. A bad one becomes your biggest headache.

And yet, most brands find their manufacturer through a Google search and a few emails. This guide walks through a more structured approach — one that helps you find the right factory, evaluate it properly, and build a relationship that lasts.

Before you contact a single factory, be clear about what you are looking for.

Product Type

What are you manufacturing? T-shirts, hoodies, sweatshirts, joggers, jackets, shirts? Different factories specialise in different product categories.

• —Knitwear factories produce jersey and fleece garments: t-shirts, hoodies, sweatshirts, joggers
• —Woven factories produce structured garments: shirts, trousers, jackets, outerwear
• —Speciality factories focus on specific niches: denim, activewear, underwear, knitwear

A factory that makes excellent hoodies may not be equipped to produce structured blazers. Match the factory to your product.

Volume

How many pieces do you need per style, per colour? This determines which factories are realistic:

• —10–50 pieces: Micro-production. Limited options — look for small workshops or white-label programmes
• —50–200 pieces: Low-volume. Family-run factories in Portugal, UK, or artisan workshops. This is our range at White Cotton
• —200–1,000 pieces: Mid-volume. Most European factories operate comfortably here
• —1,000–10,000+ pieces: High-volume. Larger factories in Portugal, Turkey, Romania, or Asian manufacturers

Quality Level

Be honest about where your brand sits:

• —Budget: Basic construction, conventional fabrics, standard decoration
• —Mid-range: Good construction, quality fabrics, professional finishing
• —Premium: Superior construction, certified organic/recycled fabrics, expert finishing, meticulous QC

Asking a premium factory for budget pricing wastes everyone's time. Asking a budget factory for premium quality is a recipe for disappointment.

Location

Where do you want to produce? This affects cost, lead times, and logistics.

• —Europe (Portugal, Italy, Turkey, Eastern Europe): Higher cost, shorter lead times, "Made in Europe" positioning. Read our country comparison guide
• —Asia (China, Bangladesh, Vietnam): Lower cost, longer lead times, higher MOQs
• —Local (your own country): Highest cost, fastest turnaround, maximum control

Industry Directories

• —Portugal Clothing Factory (portugalclothingfactory.com) — Directory of Portuguese textile manufacturers
• —Kompass — Global B2B directory with manufacturer listings
• —Maker's Row (US-focused) — Connects brands with American and international manufacturers

Trade Shows

Trade shows are the best way to meet manufacturers in person, see product samples, and evaluate quality firsthand.

• —Modtissimo (Porto, Portugal) — Twice yearly, focused on Portuguese textile industry
• —Première Vision (Paris) — The largest textile trade show in Europe
• —Texworld (Paris/New York) — Fabric and manufacturing sourcing
• —Munich Fabric Start (Munich) — Premium and innovative fabrics

Direct Outreach

Identify the manufacturing regions for your product type and contact factories directly:

• —For Portuguese knitwear: Search for factories in Barcelos, Guimarães, Braga, Vila Nova de Famalicão
• —For Turkish production: Search factories in Istanbul, Izmir, Denizli
• —For Italian luxury: Search factories in Lombardy, Tuscany, Veneto

Referrals

The most reliable way to find a good factory is through referral from another brand. If you know brands producing in your target country, ask who they work with. The garment industry is relationship-driven — a warm introduction is more effective than a cold email.

Contact 5–10 factories that match your criteria. Send each one the same brief:

• —What you want to produce (product types, descriptions)
• —Your estimated quantities per style per colour
• —Your fabric preferences (composition, weight, certifications)
• —Your decoration requirements (embroidery, printing, etc.)
• —Your timeline (when do you need finished goods?)
• —Your experience level (first collection? Experienced brand?)

What to Look For in Responses

Good signs:

• —Prompt response (within 48 hours)
• —Relevant questions about your project (they are engaged)
• —Clear information about their capabilities, MOQs, and lead times
• —Willingness to produce samples
• —Transparency about pricing structure
• —Factory address and contact details readily shared
• —Invitation to visit the factory

Red flags:

• —No response for a week or more
• —Vague answers to specific questions
• —Unwillingness to share factory location or photos
• —Pricing that seems too good to be true
• —No mention of quality control procedures
• —Pressure to commit to large orders before sampling
• —Request for large upfront payments before any work begins

Request samples from your top 2–3 factory choices. This is the most important evaluation step — everything else is words; the sample is the product.

When evaluating samples, check:

• —Fabric quality — Does it feel as specified? Is the weight correct?
• —Construction — Are seams clean, consistent, and properly finished?
• —Fit — Does it match your measurements and proportions?
• —Details — Labels, ribbing, drawcords, buttons — are they high quality?
• —Interior — Is the inside as well-finished as the outside?
• —Wash test — Wash and dry the sample. Does it shrink, twist, fade, or pill?

For a complete sampling guide, read your first clothing sample.

For European production, visiting the factory is practical and highly recommended. A factory visit tells you things that emails and samples cannot:

• —Is the factory clean and organised?
• —Are the workers engaged and the environment respectful?
• —Is the equipment well-maintained?
• —Does the production floor match what they claimed?
• —Can you see quality control happening in real time?
• —Do you trust the people you are entrusting with your brand?

At White Cotton, we actively encourage factory visits. Our facility is in Barcelos, Portugal — a 40-minute drive from Porto airport. Brands that visit are always the ones we build the strongest relationships with.

Once you have identified your preferred factory, negotiate clear terms before committing:

Pricing

• —Get a detailed breakdown: fabric, manufacturing, decoration, labels, packaging, shipping
• —Understand what is included and what is extra
• —Ask about volume pricing — what happens to the unit price at 200, 500, 1,000 pieces?

Payment Terms

• —Standard: 50% deposit on order confirmation, 50% balance before or on delivery
• —Some factories offer credit terms for repeat clients (30, 60, or 90 days)
• —Be cautious of factories requiring 100% upfront payment

Lead Times

• —Confirm sampling lead time per round
• —Confirm production lead time from sample approval to delivery
• —Build in buffer for delays

Quality Standards

• —Agree on acceptable quality level (AQL)
• —Confirm who inspects: the factory, you, or a third party?
• —Establish what happens with defective pieces (replacement, refund, discount?)

Intellectual Property

• —Ensure your designs, patterns, and tech packs remain your property
• —Confirm the factory will not produce your designs for other brands
• —If IP protection is critical, include it in your agreement

Do not put your entire first collection with a new factory. Start with one or two styles at minimum quantities. Evaluate the experience:

• —Was the quality consistent with the sample?
• —Were deadlines met?
• —Was communication smooth?
• —Were problems handled professionally?

If the first order goes well, increase your volumes and expand to more styles. Building a manufacturing relationship gradually reduces risk and builds mutual trust.

We are a family-run factory in Barcelos, Portugal. We produce hoodies, sweatshirts, t-shirts, shirts, jackets, joggers, and more — all cut and sewn in-house by our team.

We work with brands from their very first production order. Our MOQs start at 50 pieces per style, samples take 7–10 working days, and quotes are returned within 48 hours.

If you are searching for a manufacturer, reach out to us. We will be honest about whether we are the right fit for your brand — and if we are not, we will tell you that directly.
