Apparel Manufacturing Guide for Founders
Launching a clothing brand sounds simple — until you hit the wall of tech packs, fabric minimums, and grading specifications. This guide walks you through every stage of apparel manufacturing, from selecting a production model to shipping your first collection, with real costs and hard-won lessons from brand founders.

1. Types of Apparel Manufacturing
Before contacting a single factory, you need to decide which manufacturing model fits your brand, budget, and level of involvement. The three primary models differ dramatically in how much the factory handles versus what you provide.
Manufacturing Models Compared
| Model | You Provide | Factory Provides | Best For |
|---|---|---|---|
| CMT (Cut, Make, Trim) | Fabric, trims, patterns, tech pack | Cutting, sewing, finishing | Brands with sourcing experience |
| Full Package (FPP) | Tech pack, design specs | Everything: fabric, trims, production | New brands, overseas manufacturing |
| Private Label | Logo, labels, color choices | Existing designs + everything else | Fastest to market, lowest risk |
Most first-time founders should start with Full Package Production (FPP). You focus on design and the factory handles sourcing and production. The per-unit cost is 10-20% higher than CMT, but you avoid the complexity of managing multiple fabric and trim suppliers across different countries. Once you hit 5,000+ units per style, switching to CMT can save significant money.
2. Tech Packs
A tech pack is the blueprint for your garment. It tells the factory exactly what to make and eliminates ambiguity. Without a proper tech pack, you're relying on the factory to interpret your vision — and they will interpret it differently than you expect.
A complete tech pack typically costs $150-$500 per style if you hire a freelance technical designer (Upwork, CLO 3D specialists), or $300-$1,500 through a design agency. Many factories will create a basic tech pack for free if you commit to production, but these tend to lack the precision you need.
What to Include in Your Tech Pack
- Flat sketches — Front, back, and detail views with callouts for every design element (pockets, seams, closures)
- Bill of Materials — Every fabric, thread, button, zipper, label, and hang tag with exact specifications
- Colorways — Pantone references for every color. Never use screen colors — they vary wildly between monitors
- Measurements — Grade spec with measurements for every size in your range (in inches or cm, be consistent)
- Construction details — Stitch types (lockstitch, overlock, coverstitch), seam allowances, topstitching placement
- Label placement — Exact position of brand labels, care labels, size labels, and any printed tags
- Packaging spec — How garments should be folded, bagged, and boxed
Watch out
The most common tech pack mistake is vague measurements. "Medium chest width: 20 inches" is not enough. Specify the exact measurement point (1 inch below armhole, laid flat, edge to edge) and the tolerance (+/- 0.5 inch). Factories will hit the number they're given — make sure it's the right number.
3. Fabric Sourcing
Fabric is typically 40-60% of your garment cost. Choosing the right fabric and sourcing it efficiently makes or breaks your margins. Fabric is priced per yard or per meter, and costs vary wildly based on fiber content, weight (GSM), and finish.
Common Fabric Types & Costs
| Fabric | Price/Yard | MOQ (Yards) | Common Use |
|---|---|---|---|
| Cotton jersey (180 GSM) | $2 - $6 | 300-1,000 | T-shirts, basics |
| French terry (280 GSM) | $4 - $10 | 500-1,000 | Hoodies, sweatshirts |
| Organic cotton | $5 - $12 | 500-2,000 | Premium basics, eco brands |
| Polyester performance | $3 - $8 | 500-1,000 | Activewear, athleisure |
| Denim (10-14 oz) | $4 - $15 | 1,000-3,000 | Jeans, jackets |
| Nylon ripstop | $3 - $9 | 500-1,500 | Outerwear, bags |
Fabric MOQs are one of the biggest hurdles for new brands. A 300-yard minimum at $5/yard is $1,500 of fabric — enough for roughly 150-200 T-shirts in one color. If you have 4 colors, that's $6,000 in fabric alone before you've cut a single garment.
To work around high MOQs, look for fabric mills that offer stock fabric programs (Alibaba, Swatchon) or work with domestic jobbers who buy mill overruns at a markup. You can also use deadstock fabric for your first collection to test the market before committing to custom fabric orders.
Tip
Always order a 3-5 yard sample cut (called a "lab dip" for color and a "hand loom" for fabric construction) before committing to a bulk order. Test it for shrinkage, pilling, colorfastness, and hand feel after 5-10 washes. A $50 sample can prevent a $5,000 fabric disaster.
4. Sizing & Grading
Sizing is where many new brands stumble. There is no universal standard — a "Medium" varies by brand, country, and garment type. You need to define your own size chart based on your target customer and then "grade" it across your full size range.
Grading is the process of scaling a pattern up and down from your base size. If your base size is Medium, grading creates the Small, Large, and XL patterns by applying consistent increments to each measurement point. Professional grading costs $25-$75 per size per style, and it's worth every penny.
Typical Grade Rules (Men's T-Shirt)
| Measurement | S | M (Base) | L | XL | Grade |
|---|---|---|---|---|---|
| Chest (half) | 19" | 20.5" | 22" | 23.5" | +1.5" |
| Body length | 27" | 28" | 29" | 30" | +1" |
| Sleeve length | 8" | 8.5" | 9" | 9.5" | +0.5" |
Watch out
Start with 3-4 sizes (S/M/L/XL) for your first collection. Adding XXS-3XL sounds inclusive but multiplies your inventory by 2-3x and makes your first production run significantly more expensive. Expand your size range based on sales data after your first drop.
5. Production Process
A full apparel production cycle from first sample to delivered goods typically takes 12-20 weeks. Understanding the timeline helps you plan collection drops and avoid the single biggest mistake in fashion: missing your season.
Production Timeline
Week 1-2: First Sample (Proto Sample)
Factory creates the first sample from your tech pack. Made in your base size using available fabric (not necessarily your final fabric). Cost: $50-$200 per style. Expect 2-3 rounds of revisions.
Week 3-4: Fit Sample
Refined sample with fit corrections. Test on a live model that matches your target customer body. This is where you finalize measurements and construction details.
Week 5-6: Pre-Production Sample (PP Sample)
Made with final fabric, trims, and labels. This should be identical to what you'll sell. Sign off on this sample in writing — it becomes the factory's reference standard.
Week 6-10: Fabric Production & Dyeing
If you're using custom fabric, the mill needs 4-6 weeks to produce and dye it. Stock fabric ships in 1-2 weeks.
Week 10-14: Cutting & Sewing
Actual garment production. A typical factory can produce 500-2,000 pieces per week per line. Your run of 500 pieces might take 3-5 days of line time, but factories batch orders, so expect 2-4 weeks.
Week 14-16: Quality Check & Shipping
Final QC inspection (hire a third-party inspector for $200-$400/day), packing, and shipping. Ocean freight adds 3-5 weeks; air freight adds 5-7 days but costs 5-8x more.
6. Cost Breakdown
Understanding your per-unit cost structure is essential for pricing. Apparel margins are tight — most brands target a 60-70% gross margin at retail (meaning COGS is 30-40% of retail price). Here's how costs typically break down.
Cost Breakdown: Premium Cotton T-Shirt (500 units)
| Cost Component | Cost/Unit | % of Total |
|---|---|---|
| Fabric (1.5 yds @ $5/yd) | $7.50 | 45% |
| Cut & sew labor | $3.50 | 21% |
| Trims (labels, tags, thread) | $1.00 | 6% |
| Printing / embroidery | $1.50 | 9% |
| Packaging (poly bag + hang tag) | $0.75 | 5% |
| Shipping (ocean freight, allocated) | $1.50 | 9% |
| Duty (est. 16.5%) | $0.80 | 5% |
| Total Landed Cost | $16.55 | 100% |
Pricing rule of thumb
For DTC (direct-to-consumer) brands, price at 3-4x your landed cost. A $16.55 landed cost T-shirt should retail for $48-$65. For wholesale, price at 2x landed cost and let retailers mark up another 2-2.5x. If you can't hit your target retail price at 500 units, consider whether higher volume or a different fabric can close the gap.
7. Top Manufacturing Countries
Your choice of manufacturing country affects cost, quality, lead times, and minimum order quantities. Here's how the major apparel manufacturing hubs stack up.
Country Comparison
| Country | Strengths | Typical MOQ | Cost Level |
|---|---|---|---|
| China | Versatile, fast, technical fabrics | 200-500 pcs | $$ |
| Bangladesh | Lowest cost for basics, huge capacity | 1,000-3,000 pcs | $ |
| Vietnam | Activewear, outerwear, growing fast | 500-1,000 pcs | $$ |
| Portugal | Premium quality, low MOQs, EU access | 100-300 pcs | $$$ |
| Turkey | Denim, knitwear, fast turnaround | 200-500 pcs | $$ |
For startup brands doing their first run of 200-500 pieces, Portugal and Turkey offer the best combination of low MOQs and quality. Portuguese factories are especially popular with European and American DTC brands — they're experienced with small runs, communicate well in English, and produce at a quality level that justifies premium pricing ($40+ retail for a tee).
For volume production (3,000+ units), Bangladesh and Vietnam offer the best unit economics. Bangladesh dominates basic knitwear and woven shirts, while Vietnam excels at performance wear and outerwear. China remains the most versatile option and is often the best choice when you need technical fabrics or complex construction.
8. Common Mistakes & Tips
Top mistakes apparel founders make
- Too many SKUs in the first collection. Launching with 15 styles in 5 colors and 6 sizes means 450 SKUs. At 100 units per SKU, that's 45,000 units and a $200,000+ order. Start with 3-5 styles, 2-3 colors, 4 sizes.
- Not accounting for fabric shrinkage. Cotton shrinks 3-5% after the first wash. If you don't pre-shrink your fabric or add shrinkage allowance to your patterns, every garment will fit tight after the customer's first wash.
- Skipping the fit sample. Going straight from proto sample to production to save 2 weeks. This guarantees fit issues at scale that cost far more than 2 weeks to fix — returns, bad reviews, and dead inventory.
- Choosing a factory on price alone. The cheapest factory often has the highest rejection rates, worst communication, and longest delays. Get references, see samples of past work, and visit if possible.
- Ignoring duty rates. US import duties on apparel range from 5% to 32% depending on fiber content and garment type. A 20% duty on a $10 garment adds $2 per unit — at 5,000 units, that's $10,000 you didn't budget for.
Pro tips for your first collection
- Start with basics. T-shirts, hoodies, and joggers have the simplest construction and the widest market. Master production on a basic style before attempting complex garments like tailored jackets or swimwear.
- Get a wash test from the factory. Request a sample that's been washed 5 times per your care instructions. Check for shrinkage, color bleeding, pilling, and seam integrity.
- Negotiate payment terms. Standard is 30% deposit, 70% before shipping. For your first order you may need to pay 50/50, but push for 30/70 as you build trust. Never pay 100% upfront.
- Photograph the PP sample obsessively. Take 50+ photos with measurements visible. This is your legal reference if the production run doesn't match. Factories respect specificity.
