Pattern Making, Tech Pack &
Physical Sampling
Your vision is creative; factories speak in measurements. We bridge the gap with professional tech pack development, precision digital pattern making, and physical sampling—transforming rough ideas into factory-ready blueprints before a single dollar is spent on bulk production. You own 100% of every file we create.
The Factory Instruction Manual
A tech pack is the single most important document in apparel manufacturing. It is the complete instruction manual that tells the factory exactly how to make your garment—down to the millimeter. Without it, production is a guessing game that results in wasted fabric, delayed timelines, and samples that look nothing like your original idea.
A professional tech pack eliminates ambiguity. It includes flat technical sketches, detailed point measurements for every dimension, a Bill of Materials (BOM) specifying exact fabrics and trims, stitch and seam construction methods, print placement coordinates, and size grading rules. When a factory receives a proper tech pack, there is zero guesswork involved.
The cost of skipping a tech pack is far higher than the cost of creating one:
- Wrong measurements: A 2cm error on a waistband means 100+ unwearable garments in a bulk order
- Fabric mismatch: Ordering the wrong GSM or blend costs thousands in wasted material
- Construction confusion: Without seam specs, factories default to their cheapest method—not your intended quality
- No legal reference: If a factory deviates from spec, you have no documented proof to demand corrections
Whether you are launching gym wear, developing premium athleisure, or creating custom team kits, the tech pack is the foundation upon which your entire product quality is built.
Why Physical Sampling Is Non-Negotiable
A digital mockup looks great on a screen, but fabric behaves differently in real life. A design that looks proportional on a model may fit terribly on an actual human body due to fabric weight, stretch ratio, or drape characteristics. Physical sampling is the only way to verify fit before committing to a bulk order.
At Dhalay International, we don't just send you a sample and ask for a yes or no. We send you a sample so you can put it on a fit model, test the range of motion, wash it, stretch it, and compare it side-by-side with your reference garment. If the armhole is too tight or the length is too short, our pattern makers adjust the digital file and produce a revised sample until the fit is absolutely perfect.
The economics are clear: a small sampling investment protects you from a catastrophic bulk order mistake.
- A $150–$300 sampling investment protects you from a $3,000–$10,000 bulk order mistake of garments that don't fit
- Samples reveal issues that no amount of digital review can catch—fabric hand-feel, weight perception, stretch behavior, and real-world drape
- An approved sample becomes your gold standard reference for QC during bulk production—every factory piece must match it
- For complex cut and sew projects, sampling is especially critical to test multi-fabric panel alignment and structural integrity
Who Needs Tech Pack & Sampling Services
First-time apparel founders with no technical background. You have a brand idea, maybe a Pinterest board full of inspiration, but zero knowledge of garment construction. Our team translates your visual references into the precise technical documents factories require—no design degree needed.
D2C brands scaling from blanks to custom products. If you've been selling generic wholesale blanks with your logo printed on them, a tech pack is your gateway to truly custom products with your own fit, your own fabrics, and your own construction quality.
Fitness influencers and content creators. Your audience wants to wear your brand, not someone else's fit. We create custom patterns that flatter the body types your audience identifies with—whether that's muscle-fit for bodybuilding or relaxed-fit for lifestyle wellness.
Brands switching factories. If you're moving production from one factory to another, a proper tech pack ensures the new factory replicates your existing product exactly—no "close enough" interpretations that degrade your brand consistency.
The Cost of Skipping This Step
Many first-time founders try to skip straight to production with just a photo or a verbal description. Here's what typically happens:
Scenario 1: The "Just Make It Like This Photo" Approach. You send a competitor's product photo to a factory. They produce something that looks similar in a thumbnail but fits completely differently. The shoulder seam is 2cm off, the fabric is a different weight, and the hem length is wrong. You receive 200 unwearable garments.
Scenario 2: The "I'll Fix It In Production" Approach. You approve a sample that's "close enough" because you're in a hurry. The factory produces 500 pieces to that "close enough" standard. Every customer review mentions the weird fit. Your brand reputation takes a hit before you've even established it.
Scenario 3: The "I'll Do It Myself" Approach. You download a free tech pack template online and try to fill it out without understanding measurement conventions. The factory receives a document with conflicting specs, wrong terminology, and missing details. They either reject it or produce something unpredictable.
The professional approach: Invest $200–$500 in a proper tech pack and sampling cycle. Eliminate every one of these failure modes. Launch with confidence that your product fits, looks, and feels exactly as intended.
What's Inside a Professional Tech Pack
Every component a factory needs to produce your garment—nothing left to interpretation.
| Component | What It Contains | Why It Matters |
|---|---|---|
| Flat Technical Sketches | Front, back, and side views with construction detail callouts | Visual reference for every seam, panel, and design element |
| Point Measurements | 30–50 precise measurements (chest, shoulder, sleeve, hem, etc.) | Eliminates guesswork—factory knows exact dimensions for every size |
| Bill of Materials (BOM) | Exact fabric, thread, zipper, label, and trim specifications | Prevents wrong material sourcing—a $5,000 error on a bulk order |
| Stitch & Seam Map | Stitch type (flatlock, overlock, chain), SPI (stitches per inch), seam allowance | Factory defaults to cheapest method without this—your quality suffers |
| Print Placement Specs | Exact coordinates, dimensions, and color codes for every print/logo | Ensures branding is positioned correctly on every size, not just the sample |
| Size Grading Table | Mathematical grade rules from base size (M) to XS through 4XL | Proportional fit across entire size range without sampling every size |
| Construction Notes | Step-by-step assembly sequence, special instructions, tolerance limits | Complex garments (multi-panel, lined) need this to avoid assembly errors |
| Digital CAD Pattern | Industry-standard digital pattern file with seam allowances and notches | Ready for immediate plotting and cutting—no factory redrafting needed |
| Approved Physical Sample | Actual sewn garment in specified fabric with all trims attached | The gold standard reference for bulk QC—every piece must match this |

Our Development Capabilities
From a rough sketch to a production-ready blueprint—we handle the entire pre-production phase.
Tech Pack Creation
Have an idea but no technical document? Send us your mood boards, reference images, or rough sketches. Our technical designers will create a comprehensive, factory-grade tech pack with all required specifications for production.
Digital Pattern Making
We draft precise digital blocks on industry-standard CAD software. Every seam allowance, notch, grain line, and construction marker is digitized for perfect replication during bulk cut and sew production.
Size Grading
We develop your base pattern (usually size M), then mathematically grade it up and down to XS–4XL with proportional grade rules. This ensures consistent fit across your entire size range without requiring a physical sample for every size.
Physical Prototyping
We cut and sew a physical sample in your chosen fabric. This lets you test the actual hand-feel, weight, stretch, and fit on a real body—something digital rendering cannot accurately simulate, especially for stretch fabrics.
Pattern Revision Rounds
Samples rarely arrive perfect on the first try—and that's expected. We include revision rounds in our service. Based on your fit model feedback, we adjust the pattern and produce an updated sample until you sign off.
Reverse Engineering
Have a competitor's garment that you love but want to improve upon? Send it to us. We deconstruct it, measure every dimension, analyze the construction, and create a new tech pack with your custom modifications and improvements.
100% IP Ownership
Every file we create—CAD patterns, measurement sheets, tech pack PDFs—belongs to you. No licensing fees, no usage restrictions. Take your files to any factory in the world. We earn your business through quality, not lock-in.
Bulk Production Credit
If you proceed to bulk production with Dhalay International after development, your entire tech pack and sampling cost is credited toward the bulk order. Your development investment becomes effectively free.

The Development & Sampling Process
A structured, iterative workflow designed to eliminate errors before bulk production begins.
Brief & Research
We analyze your references, target market, and price point. We recommend fabrics, fits, and construction methods that align with your brand positioning and production budget.
Tech Pack Drafting
Our technical designers create flat sketches, define all point measurements, build the Bill of Materials (BOM), and specify stitch types and print placements. You review and approve the digital draft.
Pattern & Prototyping
Digital patterns are drafted from the approved tech pack. A physical sample is cut, sewn, and finished with all specified trims—zippers, labels, ribbing—to match the final production version exactly.
Fit Review & Revision
The sample is shipped to you for fit testing on a real body. You provide feedback. We adjust the pattern and produce an updated sample if necessary until you are 100% satisfied with the fit.
Bulk Handoff
The finalized tech pack, graded patterns, and approved sample are handed over to our production floor—or exported to your chosen factory—as the master blueprint for bulk manufacturing.

What Our Development Clients Say
Real feedback from founders who used our tech pack and sampling service to launch their brands.
"I had zero apparel knowledge—literally just a Pinterest board and a brand name. Dhalay turned my vague inspiration into a 12-page tech pack and a physical sample that fit perfectly on the first revision. I now have 6 styles in production and every one started from their tech packs."
"We had a terrible experience with another factory that produced 300 hoodies that looked nothing like our reference. Dhalay created a proper tech pack and sample first—the bulk order matched the sample exactly. That $300 tech pack saved us from another $4,000 mistake."
"I sent them a Lululemon legging to reverse engineer with custom modifications—longer inseam, different waistband, our own fabric. They deconstructed it, created a complete tech pack with my changes, and the sample was closer to my vision than I imagined possible. The CAD files are now with my factory in Vietnam."
