Summary
Discover the essential steps to submit your clothing designs to manufacturers with our expert guide. Turn your fashion ideas into reality today!
Submitting your clothing designs to a manufacturer is where creativity meets execution — and it’s the moment that decides whether your idea becomes a wearable hit or a costly lesson. Many indie designers and boutique owners assume the “submission” is just an email with sketches.
In reality, it’s a structured process that mixes technical documentation, clear communication, and the right partner. Miss one piece — unclear specs, the wrong file type, or poor choice of manufacturer — and you’ll face expensive reworks, delayed shipments, or quality problems that damage your brand.
To submit designs effectively, prepare a complete tech pack (measurements, construction details, fabric and trims list, color references, and fit notes), provide files in manufacturer-friendly formats (AI/PDF/JPG/PLT), and deliver physical swatches or samples if possible. Choose an appropriate submission channel (email with cloud links, a factory portal, or physical courier), confirm the manufacturer’s capabilities, and start with a clear sample and approval workflow to avoid costly miscommunication.
I once worked with a designer who sent a single phone photo of a pair of jeans and hoped for the best; they received a mismatched wash, wrong hardware, and a fit that barely fastened.
After three costly trips back and forth, we rebuilt a tech pack and switched to a denim-specialist factory — and the resulting collection sold out in three weeks. Read on to learn the step-by-step system that keeps your designs from becoming “that” sample.
What paperwork and digital files should I prepare before contacting a manufacturer?
Before contacting a factory, assemble a complete tech pack including spec sheet, construction notes, BOM (bill of materials), color/Pantone references, trim/hardware callouts, grading rules, and clear flat sketches. Supply file formats the factory accepts (AI, PDF, DXF, high-res JPG/PNG) and physical swatches where possible. Include clear labeling, version control, and a short cover email summarizing key points and deadlines.
A tech pack is the single most valuable artifact you’ll give a manufacturer — it’s the blueprint they’ll use to price, cut, sew, and QC your product. Think of it as both your engineer’s drawing and your lawyer’s contract: precise, unemotional, and complete.
Core elements to include:
Spec sheet / measurement chart: Front waist, back rise, inseam, thigh, knee, hem, pocket placement, topstitching distances. Use clear units (cm or inches) and list tolerances (± values).
Construction details: Type of stitch, stitch density (stitches per inch), seam allowances, bartack locations, pocket bags, fly type (zip or button), and lining instructions.
Bill of Materials (BOM): Fabric composition, GSM (grams per square meter), supplier references or fabric codes, trims (buttons, rivets, zippers with part numbers), labels, hangtags, and packaging.
Color references: Pantone numbers, fabric dye recipe if known, and photos of desired wash/finish. For denim, include wash methods (enzymatic, stone, whisker patterns) and reference photos.
Grading rules: Base size measurements and the grade increments for each size up/down the range; if you don’t have a grader, state your intended fit profile (e.g., high-rise boyfriend, relaxed tapered).
Fit notes and model photos: Provide annotated photos showing where you want changes in fit, and a fit model spec (height, bust/waist/hip).
Label & compliance info: Care label wording, country of origin statement, fiber content, and any required regulatory markings.
File types and sending method:
Vector files: Adobe Illustrator (.AI or .PDF with layers) for tech drawings and pattern details.
Raster files: High-res JPG/PNG for mood images and wash references.
CAD/DXF for pattern outlines if your factory accepts them.
BOM and spec sheets: Excel or Google Sheets — the factory will often ask you to fill in their template for costing.
Physical items: Whenever possible, send fabric swatches (5x5” minimum), trim samples, and a master sample garment. For denim, send pre-washed swatches so shrinkage and hand are evident.
Version control and naming:
Use a simple but consistent system: [BrandName_StyleCode_v01_Date.pdf]. Keep one shared cloud folder (Google Drive/Dropbox/WeTransfer) and update only one file with a clear changelog.
Practical checklist:
Tech pack (complete)
BOM (with supplier references)
Flat sketches with callouts
Spec sheet + grading rules
Fabric + trim swatches
Color references (Pantone)
Fit photos + model specs
Preferred file formats and shipping address
Why this level of detail matters:
Manufacturers price and schedule work around how clearly they can interpret your request. A tidy tech pack reduces ambiguity, shortens lead time, and cuts surprises in costing. Factories also tend to trust professional-looking documentation — it signals you’re serious and ready to scale.
How do I choose the right manufacturer and verify their capabilities?
Select a manufacturer based on technical capability, capacity, MOQ, communication, and compliance. Vet via references, factory photos, audit reports, production samples, and trial orders. Decide between OEM (you supply specs), ODM (factory offers designs), and CMT (cut-make-trim) depending on how much you control. Use sourcing platforms, trade shows, or agents to find reputable denim specialists with the processes you need.
Choosing the right manufacturer is less about price and more about fit — technical fit, cultural fit, and capacity fit. Here’s how to evaluate and verify reliably.
1. Understand partnership models:
CMT (Cut, Make, Trim): You provide the fabric and trims; manufacturer cuts and sews. Best when you control fabric sourcing.
OEM (Full-package): Manufacturer sources materials and produces to your tech packs and labels. Good for convenience and end-to-end supply.
ODM (Design + Manufacture): Factory proposes designs based on your direction. Useful for private-label sellers without in-house designers. Which to choose? If you’re a design-driven brand wanting unique fabrics/washes (common in denim), OEM or CMT with a denim-specialist factory is typical. If you prefer quick-turn, private-label options, consider ODM.
2. Where to find manufacturers:
Online marketplaces: Alibaba, Global Sources, Made-in-China. Good for initial discovery but vet carefully.
Industry platforms: Makers Row, Sewport, or local sourcing directories.
Trade shows: Magic Las Vegas, Première Vision, Kingpins for denim.
Referrals & agents: Trusted industry contacts or resident sourcing agents in China can pre-screen factories.
3. Key vetting questions:
What’s your MOQ for this product type (and for custom trims)? Note DiZNEW’s MOQ starts at 30 pieces, scaling to 10,000+ for full production runs — valuable for brands that want small initial runs.
What is lead time for sample, pre-production, and bulk orders?
Can you show samples of similar products (stacked jeans, selvedge, stonewash, etc.)?
What fabrication and finishing equipment do you have (e.g., sanforizing, indigo rope dyeing, laser distressing, sanforized denim, selvedge looms)?
Certifications and compliance: BSCI, ISO, OEKO-TEX, GOTS — ask for copies.
Quality control process and inspection reports (AQL standards, in-line inspections, final inspections).
4. How to verify:
Request photos and videos of the factory floor, machines, and sample rooms.
Ask for sample garments and check workmanship, measurements, hardware quality, and wash consistency.
Contact previous clients for references, especially ones producing similar denim items.
Consider a third-party audit or inspection (Intertek, SGS) for larger orders or ongoing relationships.
5. Red flags:
Vague answers about capacity or QA.
Reluctance to provide sample photos, previous clients, or certifications.
Extremely low quoted prices without clarity on fabric or workmanship assumptions — likely corners being cut.
6. Prioritize communication and timezone alignment:
Sample Content
How do I manage samples, fit approvals, and pre-production checks?
Manage samples through a staged sample process: prototype → fit sample → pre-production (PP) sample → first article. Provide clear feedback with annotated photos, measurement tables vs spec sheet, and change logs. Require lab dips or wash cards for color/wash approval, and confirm sample sign-off in writing before bulk production to avoid rework.
Well-run sampling is where most quality and fit issues are caught — it’s cost-effective to catch mistakes before bulk runs begin. Here’s a practical roadmap.
1. Sample stages explained:
Prototype / Initial sample: A first try to interpret your design. Expect proportion and construction issues; this is exploratory.
Fit sample: Focused on sizing and silhouette. Should be made in base fabric or a close substitute; used for model fittings and measurement verification.
Pre-production (PP) sample: Made with production-grade fabrics, hardware, and wash. This is the near-final sample and should match bulk production as closely as possible.
First Article / Golden Sample: Final approved standard that the factory must match for the production lot; kept as QC reference.
2. What to include when you request samples:
Tech pack and BOM (clearly referenced)
Target ship date for sample and turnaround expectations
Physical fabric swatches and trim samples
A clear list of fit points you want assessed
A sample approval form / checklist with sign-off boxes (fit, color, wash, hardware, labeling)
3. How to give clear feedback:
Use a measurement comparison table: column A = spec/target; column B = sample measurement; column C = difference (+/-); column D = corrective action.
Annotate photos — circle problem areas (e.g., gaping at back waist, bunching at crotch) with short notes.
Record small video clips showing fit on a model to illustrate movement and drape.
Keep a change log: list revisions, who authorized them, and the date.
4. Denim-specific approvals:
Lab dips / strike-offs: For precise indigo or dye shades, approve strike-offs before yardage dyeing.
Wash/method cards: For each wash recipe provide expected color, abrasion areas, hand-feel, and rinse-down photos. Approve one wash-run sample per batch if wash consistency is critical.
Shrinkage/hold tests: Pre-production yardage needs shrinkage data so grading and spec sheets are accurate — especially important for denim which can shrink 2–5% or more depending on processing.
5. Common pitfalls and how to avoid them:
Skipping the PP sample and doing a bulk run: Produces mismatched batches and unexpected costs.
Vague fit notes: “Make it fit better” is useless — show precise measurements and reference garments.
Ignoring trim and hardware: Buttons and zippers can vary widely in look and durability; approve a physical sample.
Not confirming packaging: Hangtags, poly bags, and folding instructions matter for retail presentation and shipping costs.
6. Timeline and cost considerations:
Typical sample turnaround: Prototype 7–14 days; Fit sample 7–10 days; PP 10–21 days depending on wash and fabric.
Budget for samples: Small designers should expect $50–300 per sample for simple items and $150–600+ for complex denim washes and hardware. Denser wash and distress work ups cost more.
Sample process is iterative. Treat it like a sprint: clear expectations, quick feedback, and documented approvals reduce delays and cost overruns.
How should I negotiate commercial terms, timelines, and quality control?
Negotiate based on clear line items: fabric cost, trims, labor, washing/finishing, packaging, and freight. Clarify MOQ, price breaks, lead times, payment terms (deposit, balance), and AQL acceptance levels. Include change-order rules and penalties for late delivery or subpar quality. Use a concise contract and attach the approved golden sample and tech pack as contractual reference.
Negotiation is a business conversation where transparency and clarity protect both parties. Here’s how to approach terms practically.
1. Break down the price components:
Fabric (per meter/yard), including selvedge premium or special denim
Trims and hardware (per unit)
Cutting and sewing labor (per piece)
Washing and finishing (per wash or per piece depending on method)
Packaging (poly bags, boxes, hangtags)
Overhead (pattern making, sample charges, strike-offs)
Freight and duties (FOB, CIF, DAP terms affect cost)
2. MOQ and price breaks:
MOQ affects your unit price. A typical denim factory like DiZNEW accepts small custom runs (MOQ 30) but provides better unit pricing at larger volumes (e.g., 500, 2,000, 10,000).
Ask for a price break table: list unit price at resource breakpoints so you can plan inventory and pricing strategies.
Example price-break table (illustrative)
| Quantity | Unit Price (USD) |
| 30 | 45.00 |
| 100 | 30.00 |
500 | 18.00 |
| 2000 | 12.00 |
3. Lead times and scheduling:
Define sample lead time, PP lead, and bulk production lead. Include buffer for shipping and customs.
Negotiate penalties or expedited options for late delivery if timing is critical.
4. Payment terms and risk:
Common models: 30% deposit on order, 70% balance before shipment. For larger, long-term partnerships, consider payment milestones or LC (Letter of Credit).
For first-time relationships, use smaller initial orders and incremental increases to build trust. Escrow or third-party payment protection can be used.
5. Quality control and acceptance criteria:
Agree on AQL (Acceptable Quality Level) for defects — e.g., AQL 2.5 for major defects, AQL 4.0 for minor defects is typical.
Include sample-based acceptance: production must match the golden sample; any deviance requires corrective runs.
Establish in-line inspections and pre-shipment inspections, and who pays for rework if QC fails.
6. Change orders and scope creep:
Put change order terms in writing: any changes after sample approval should have cost and lead-time implications and require written sign-off.
Small changes (trim color) may be allowable; structural changes (pocket design) should be treated as new samples.
7. Legal protections:
Include IP clauses, non-compete on design, confidentiality, and terms for handling defective lots.
For recurring orders, a Master Supply Agreement with style-specific appendices is efficient.
Commercial negotiations are long-term investments. Factories appreciate customers who are organized, realistic about costs and timelines, and consistent with approvals and payments.
How can I protect my designs and communicate effectively during production?
Protect designs with NDAs, design copyright where available, and clear contractual IP clauses. Communicate through a single point of contact, shared folders (with version control), and regular production updates. Use factory portals or project boards for milestone tracking, and ensure change orders are documented. For high-value denim features, register unique trims or logos and insist on confidentiality in vendor contracts.
Design protection and communication are inseparable — the clearer and more secure your information flow, the lower the risk of leaks, errors, and delays.
1. Intellectual property (IP) basics:
Copyright protects original creative works (e.g., a unique print or graphic). Clothing design copyright varies by country; small elements (functional design) are harder to protect.
Trademark your brand name and logos; this is straightforward and enforceable.
Design patents (or registered designs) can protect unique ornamental features in some jurisdictions, but they’re costly and take time.
2. Using NDAs and contracts:
NDAs: Use them when sharing tech packs with suppliers who might copy designs. Ensure the NDA specifies confidential items, duration, and remedies for breach.
IP clauses: In sourcing contracts, include clauses that explicitly state the factory will not reproduce, sell, or share your designs, trims, or labels without permission.
For high-risk styles (signature wash or unique hardware), request that the supplier restrict production to your approved PO numbers and labels.
3. Communication systems that work:
Single point of contact: A designated brand rep and a dedicated factory AM/tech team reduce confusion.
Shared folders: Use one cloud folder per style with subfolders: tech pack, samples, approvals, photos, and shipment docs. Use clear naming and a changelog file.
Project management tools: Trello, Asana, or dedicated PLM systems can track milestones, approvals, and responsibilities. For smaller teams, a shared spreadsheet with status columns often suffices.
Messaging etiquette: Use email for formal approvals and WhatsApp/WeChat for quick clarifications, but always follow up with written confirmation for decisions.
4. Production updates and escalation:
Ask for regular updates: cut plan confirmation, in-line inspection reports, wash batch photos, and pre-shipment photos of cartons and labels.
Define escalation steps for issues: immediate notification, proposed corrective actions, and timeline for resolution.
5. Handling mid-production changes:
Change orders must be written and signed by both parties. Expect cost and lead-time impacts.
For critical items (e.g., color or hardware), freeze changes after PP sample approval unless both parties sign off.
6. When to involve legal or third parties:
If you suspect IP theft, document all evidence and consult IP counsel. For urgent quality failures, a third-party inspection company (SGS, Intertek) can independently verify defects and provide evidence.
7. Practical tips to reduce risk:
Start with smaller runs to validate the relationship.
Limit how many outside vendors receive complete tech packs (share only what’s needed).
Keep unique hardware or labels in limited supply and under your control where possible.
The better your systems for protection and communication, the faster you’ll scale with fewer surprises. Factories like DiZNEW that specialize in denim expect these conversations and can adapt their workflows to protect your designs while delivering quality.
