Cut and Sew Manufacturing Guide: Process, Sourcing, and Factory Selection
Cut and sew is the process of taking raw fabric, cutting it into pattern pieces, and sewing those pieces into a finished garment from scratch. If you want to create custom apparel (your own designs, your own fabrics, your own fit), this is the production method that makes it possible.
Unlike printing on blank garments or adding embroidery to off-the-shelf items, cut and sew gives you full control over every detail: silhouette, fabric weight, stitching, labels, and construction. It is the standard method for producing everything from streetwear and activewear to uniforms, outerwear, and private-label fashion lines.
I have sourced hundreds of cut-and-sew apparel products for clients at Cosmo Sourcing since 2012, working with garment factories across Vietnam and China. This guide covers how the process actually works, what to look for in a manufacturer, where to source production, and the common mistakes I see buyers make.

What Is Cut and Sew Manufacturing?
Cut and sew is a garment manufacturing method in which products are made entirely from raw materials rather than customized from pre-made blanks. A factory receives your design specifications (typically in the form of a tech pack), sources or receives your chosen fabrics, cuts the fabric into component pieces using patterns, and sews those pieces into finished garments.
How It Differs from Other Apparel Production
The distinction matters because not all "custom" apparel is truly custom. Here is a quick comparison:
Cut-and-sew: Garments are made from scratch using your patterns and fabrics. You control the fit, construction, materials, and every design detail. This is true custom manufacturing.
Print on demand/decoration: A manufacturer takes a pre-made blank garment (typically a t-shirt, hoodie, or hat) and adds your design through screen printing, DTG printing, or embroidery. You are customizing the graphic, not the garment itself.
Private label on blanks: Similar to decoration, but you add your own brand labels to pre-existing garments. The underlying product is not custom.
If you need a unique fit, a proprietary fabric, a non-standard silhouette, or construction details that set your product apart, cut-and-sew is the method for you.
What Products Use Cut and Sew?
Nearly any sewn product can be manufactured through the cut-and-sew process. The most common categories include:
Apparel
T-shirts, hoodies, joggers, dresses, button-downs, jackets, outerwear, swimwear, underwear, and uniforms.
Activewear and Performance Wear
Leggings, sports bras, compression garments, yoga pants, and moisture-wicking tops. Vietnam, in particular, has built significant capacity in this category, producing for brands like Nike, Adidas, and Lululemon. See our guide to activewear manufacturers in Vietnam for more details.
Accessories and Soft Goods
Bags, hats, gloves, and other sewn accessories that require pattern cutting and assembly.
How the Cut and Sew Process Works
If you are placing your first cut-and-sew order, here is what the production process typically looks like from the buyer's side.
Design and Tech Pack Development
Everything starts with your tech pack. This is the technical document that tells the factory exactly what to produce. It includes flat sketches (front, back, side views), measurements and grading for each size, a bill of materials listing all fabrics, trims, zippers, buttons, labels, and elastic, construction details specifying stitch types, seam allowances, and finishing methods, and colorway specifications.
A good tech pack is the single most important factor in getting an accurate sample. Factory prices are based on the tech pack, so if yours is vague, expect vague quotes. I have seen clients save weeks of back-and-forth simply by investing time upfront in a clear, detailed tech pack.
Sampling
Before any bulk production, the factory produces one or more samples for your approval. This typically includes a first sample (also called a development sample or proto) to check fit, construction, and overall design. After you review and provide feedback, the factory makes a revised sample addressing your corrections. Once the sample is approved, a pre-production sample confirms the final version before the production run begins.
Sampling is not free. Expect to pay for each sample, and plan for two to three rounds of revisions as a standard part of the process. Rushing this step is one of the most common and expensive mistakes in garment sourcing.
Fabric Sourcing and Cutting
Once the sample is approved and a production order is placed, the factory sources fabric (either from their own supply chain or from a supplier you specify). The fabric is inspected, spread on cutting tables, and cut into pattern pieces. Most modern factories use automated cutting machines (CAD-driven cutters), which improve accuracy and reduce fabric waste. Smaller or more specialized operations may still use manual cutting for certain fabrics or low-volume runs.
Sewing and Assembly
Cut pieces are moved to the sewing floor, where operators assemble the garment according to the construction specifications in your tech pack. This is the most labor-intensive stage, and it is where a factory's skill level shows. Complex garments (multi-panel jackets, garments with linings, technical activewear with bonded seams) require more experienced operators and more specialized machinery than basic t-shirts or shorts.
Finishing and Quality Control
After sewing, garments go through finishing: thread trimming, pressing or steaming, label attachment, folding, and packing. Quality control inspections happen throughout the process, but the final inspection before packing is critical. Most professional buyers also arrange a third-party inspection (e.g., SGS, Bureau Veritas, or QIMA) before shipment to verify quality against the specifications.
What to Look for in a Cut and Sew Manufacturer
Finding a factory that can produce your product is one thing. Finding a factory that can produce it well, on time, and at a price that works for your business is another challenge. Here are the criteria that matter most.
Product Specialization
Garment factories specialize. A factory that excels at woven dress shirts may not be the right fit for performance leggings. Look for manufacturers with demonstrated experience in your specific product category. Ask for photos or samples of similar products they have produced.
Minimum Order Quantities
MOQs vary widely in cut-and-sew manufacturing. Large factories serving global brands may require 3,000 to 10,000 pieces per style per color. Mid-size factories often work with MOQs of 300 to 1,000 pieces. Smaller workshops or sample-focused operations may accept 50 to 200 pieces, typically at a higher per-unit cost.
Your order volume will determine which manufacturer tier is the right fit. Trying to work with a large-scale factory on a 200-piece order usually results in either a rejection or inflated pricing.
Certifications and Compliance
Depending on your market, you may need your factory to hold specific certifications. Common ones in the garment industry include OEKO-TEX (textile safety), GOTS (organic textiles), BSCI or WRAP (social compliance), and ISO 9001 (quality management). If you are selling to major retailers, they will often require specific factory certifications before they approve your supply chain. Ask about certifications early in the vetting process rather than discovering gaps after you have committed to a supplier.
Communication and Responsiveness
I cannot overstate how much this matters, especially when working with factories overseas. Language barriers, time zone differences, and cultural communication styles can lead to costly production errors. Evaluate how quickly a factory responds during the quoting and sampling phase, because that is usually their best behavior. If communication is slow or unclear before you place an order, it will only get worse during production.
Pricing Transparency
Get itemized quotes that break down fabric cost, trim cost, CMT (cut, make, trim) cost, and any additional charges for washing, printing, or special finishing. A single lump-sum price makes it difficult to identify where costs can be optimized and creates room for hidden markups.
Where to Source Cut and Sew Manufacturing
The country you source from depends on your product type, order volume, budget, and target market. Here is a practical overview of the most common options.
Vietnam
Vietnam is one of the world's top three garment exporters, with textile and apparel exports reaching $44 billion in 2024 (source: VITAS). The country has deep expertise in activewear, casualwear, outerwear, and technical garments. Vietnam's advantages include a large, skilled garment workforce, competitive labor costs, and favorable trade agreements (CPTPP, EVFTA) that reduce or eliminate tariffs for exports to many markets.
I have visited hundreds of garment factories across Vietnam's manufacturing clusters in Ho Chi Minh City, Binh Duong, Dong Nai, and the northern provinces around Hanoi. The quality of cut-and-sew production here is strong, particularly for knit apparel and performance wear. Many factories that produce for Nike, Adidas, Lululemon, and Columbia are located in Vietnam, and the technical capabilities have filtered down to mid-size factories that work with smaller brands as well. See our full guide to clothing manufacturers in Vietnam for a deeper look at the landscape.
China
China remains the world's largest garment exporter and offers unmatched scale, material availability, and manufacturing diversity. If you need specialized fabrics, complex constructions, or very large production volumes, China's supply chain depth is hard to beat. The trade-off is that tariff exposure varies significantly by importing country, and costs have risen in coastal manufacturing regions. Many buyers now use China for categories where its supply chain advantages are strongest (woven garments, technical outerwear, denim) while diversifying to Vietnam or other markets for knits and basics. Tariffs and duties change frequently, so always check the latest rates for your specific market before committing to a production location.
Other Markets
Bangladesh is strong in basics and high-volume casualwear at very competitive pricing, though lead times tend to be longer. India offers good options for woven garments, embroidery-heavy products, and organic cotton apparel. Turkey and Portugal are viable for brands targeting the European market and needing shorter lead times, though production costs are significantly higher than in Asia. For brands exploring sustainable and ethical garment manufacturing, Vietnam has invested heavily in certified green factories and eco-friendly production lines.
Common Mistakes When Sourcing Cut and Sew
After more than a decade of sourcing apparel for clients, these are the mistakes I see most often.
Skipping the Tech Pack
Sending a factory a sketch or a photo of a competitor's product and asking for a quote is not a tech pack. Without detailed specifications, the factory is guessing, and their guess will not match your expectations. Invest in a proper tech pack before you reach out to manufacturers.
Choosing a Factory Based on Price Alone
The cheapest quote usually comes from a factory that either does not fully understand your requirements or plans to cut corners on materials and construction. The cost of a failed production run (unsellable inventory, lost time, damaged brand reputation) always exceeds the savings from choosing the lowest bidder.
Underestimating Lead Times
From initial inquiry to delivery, a typical first order takes 3 to 6 months. That includes quoting, sampling (two to three rounds), fabric procurement, production, quality inspection, and shipping. If you are working toward a specific launch date, start the sourcing process much earlier than you think you need to. Returning clients with established factory relationships can shorten this timeline, but first orders almost always take longer than expected.
Not Requesting a Pre-Production Sample
After approving the development sample, some buyers skip the pre-production sample to save time. This is risky. The pre-production sample confirms that the factory can replicate the approved sample using production-grade materials and methods. Skipping it means you will not catch discrepancies until the bulk run is complete.
Trying to Manage Everything Directly Without Experience
Sourcing apparel overseas involves navigating language barriers, factory vetting, price negotiation, quality control, compliance, and international logistics. If this is not your core competency, working with an experienced sourcing company can save you significant time, money, and mistakes. Understanding how product sourcing works before your first order will help you set realistic expectations and avoid the most common pitfalls.
