Tech Stack Made Simple for Clothing Brands

ByMark Wassink

You’re sending five physical samples to your manufacturer in Bangladesh this month. Two don’t fit, one has the wrong fabric, and your deadline is three weeks out. Meanwhile, your tech pack lives in three different email threads, your pattern maker can’t open your files, and you’re not sure if this round of changes will actually fix the grading issues.

Sound familiar?

Most clothing brands don’t fail because they lack design software. They fail because they buy the wrong stack, implement it poorly, or never measure whether it actually solved the problem. This guide helps you avoid that.

Who this is for

This isn’t for teams chasing buzzwords or collecting software licenses. It’s for apparel brands, from two-person studios to multi-brand groups, that want:

  • Fewer physical sample rounds
  • Tighter specs that suppliers actually follow
  • Faster approvals without endless email threads
  • Proof that your tools deliver ROI

What you need to bring:

  • One specific bottleneck you’re willing to attack
  • Permission to run a one-season pilot
  • A spreadsheet to track before-and-after metrics

If you’re just exploring, bookmark this and come back when you’re ready to commit.

Start here: match tool to pain

Your first decision should solve a real problem, not check a feature box. Pick the bottleneck that’s costing you the most time or money right now:

Too many physical samples eating your budget?
Start with 3D design (CLO 3D or Browzwear VStitcher)

Fit issues, grading errors, or fabric waste?
Go to pattern CAD (Gerber AccuMark, Lectra Modaris, or TUKAcad)

Spec chaos with suppliers who ignore your emails?
Standardize in Techpacker

Multiple teams, suppliers, and seasons stepping on each other?
Add PLM when governance becomes the bottleneck (Centric or Backbone)

One tool. One problem. One season.

Perfect! Dan begin ik met Deel 1: Opening + Framework (tot en met Step 4)

One tool. One problem. One season.

Step-by-step: choosing your stack

This framework keeps you focused. Follow it in order, don’t skip steps, and record your baseline before you touch any software.

Step 1: Define success (with numbers)

Success needs a scoreboard, not opinions. Pick two metrics for next season and write down last season’s baseline:

  • Sample rounds: How many physical iterations before approval?
  • Approval cycle time: Days from first design to final sign-off
  • Marker yield: Fabric utilization percentage
  • Late fit defects: Issues caught after production started

Example: “Last season we averaged 4.2 sample rounds per style and 47 days to approval. Target: 2.5 rounds, 28 days.”

Step 2: Pick one category for your pilot

A pilot should be big enough to prove value but small enough to control variables. Choose one product category for one season:

Do not expand to other categories until you hit your targets. Diluting focus dilutes results.

Step 3: Select your first tool

One tool attacks one bottleneck. You can add complementary tools later, but starting with three tools at once is a recipe for half-adoption and wasted licenses.

If samples are your pain:
CLO 3D or Browzwear VStitcher

If patterns and grading are your pain:
Gerber AccuMark, Lectra Modaris, or TUKAcad

If you need design tools:
Adobe Illustrator for professional graphic designs, Canva for quick mockups

If spec communication is your pain:
Techpacker

Step 4: Lock naming conventions and libraries

Tools fail when data is messy. Before you create your first file, standardize:

Naming pattern:
category-style-season-version
Example: denim-slim-fw26-v3

Shared libraries:

  • Digital avatars (body measurements, poses)
  • Material swatches (fabric properties, colors)
  • Pattern blocks (base templates for each category)
  • Trims and hardware (buttons, zippers, labels)

If you’re using CLO 3D, store these in CLO-SET so your team works from one source. If you’re using pattern CAD, create a shared network drive with clear folder structure.

Pro tip: Assign one person as library owner. Monthly reviews catch drift before it becomes chaos.

Step 5: Keep vectors in one place

Vectors for flats, trims, prints, and typography designs need consistency. If your designer uses Illustrator, your tech pack person uses a different tool, and your supplier can’t open either file, you’ve created a bottleneck.

Centralize all vector work in one application so hand-offs stay clean across your stack.

Use Adobe Illustrator for all vector work:

Why Illustrator?
It integrates directly with Techpacker, PLM systems, and can export clean files for manufacturers. Even if you start designs in Canva or Procreate, finalize production files in Illustrator.

File organization:
Store vectors in a shared folder with the same naming convention you use for everything else: category-style-season-version.ai

This prevents the “which version did we send?” problem three weeks before production.

Step 6: Decide when to add PLM

PLM (Product Lifecycle Management) adds governance, visibility, and a single source of truth. But it’s overkill for small teams and expensive to implement poorly.

Add PLM when:

  • Multiple teams work on overlapping seasons
  • You manage 5+ suppliers across different countries
  • Compliance and approvals require audit trails
  • Spreadsheets cause more problems than they solve

Don’t add PLM when:

  • You’re a solo founder or team of 3
  • You haven’t proven ROI on simpler tools first
  • Your naming conventions are still a mess

Evaluation:
Centric covers broad fashion processes and is built for governance-heavy workflows.
Backbone is designer-friendly and offers a growth path from product development into retail operations.

Run a one-season pilot with your pattern CAD, 3D tool, and Techpacker first. If cross-functional friction persists after that, scope PLM.

Step 7: Measure and iterate

After one season, pull your KPIs and compare them to baseline. You defined success in Step 1. Now check if you hit it.

Green lights (scale the tool):

  • You hit at least two of your targets
  • The team actually uses the software
  • Suppliers adapted without major friction

Yellow lights (fix before scaling):

  • You hit one target but not others
  • Adoption is inconsistent across the team
  • Libraries are messy or naming drifted

Red lights (pause and diagnose):

  • No measurable improvement
  • Team reverted to old workflows
  • Data quality is worse than before

If you see yellow or red:
Don’t buy more licenses. Fix naming conventions, run refresher training, or assign a tool owner who can enforce standards. Then run another category through the same pilot.

If you see green:
Add one more tool category (e.g., if you piloted 3D, now add pattern CAD) or expand to a second product category. Keep measuring.

Deep dive by category

If you want a quick survey of your options before committing, use this section to sanity-check your short list and click through to the vendors you’ll trial.

Graphics and design software

Design software is where your collections start. Whether you’re creating graphic designs, typography designs, or photography-based designs, you need tools that can handle both creative exploration and production-ready files.

Adobe Illustrator: Industry standard for vector work. Use it for technical flats, print designs, logos, and any graphic that needs to scale without losing quality. Integrates cleanly with Techpacker and PLM systems. Essential if you’re working with manufacturers who need precise technical drawings.

Adobe Photoshop: For photo editing, raster graphics, and image manipulation. Use it when working with photography designs or creating complex compositions that blend photos and graphics.

Canva: Beginner-friendly tool for quick mockups, social media content, and early-stage design exploration. Not suitable for production files, but excellent for testing concepts before investing time in Illustrator. Great for creating content and marketing materials.

Procreate: iPad app for hand-drawn designs and illustrations. Perfect for creating original artwork that you’ll later vectorize in Illustrator. Popular for custom graphics and artistic approaches to designing.

When to use what:
Start concepts in Canva or Procreate, finalize production files in Illustrator, and use Photoshop for any photo-heavy work. Keep all final vector files in Illustrator so your entire team works from one source.

3D design and virtual sampling

3D simulates drape, fit, and materials to cut physical sampling and accelerate approvals. Pilot on one product family to prove value before rolling out to your entire seasonal collection.

CLO 3D: Fast, realistic fabric simulation with strong rendering capabilities. Best for brands that need to visualize hoodies, tshirts, or complex outerwear before cutting samples. Scale with CLO-SET for team collaboration and library management.

Browzwear VStitcher: Production-oriented workflows with structured onboarding via Browzwear University. Better for teams that need tight integration with pattern CAD and manufacturing processes.

Optitex: Unified 2D and 3D solution for brands that want one vendor across both pattern making and virtual sampling. Reduces the number of integrations you need to manage.

Use case: If you’re spending €5,000+ per season on physical samples that get rejected for fit or color issues, 3D pays for itself in two seasons. Start with core garments like tees and sweaters where you have the most volume.

Pattern making and grading (2D/3D)

Pattern CAD controls block quality, grading logic, marker efficiency, and fabric yield. Choose based on your existing pattern library and the level of automation you need.

Gerber AccuMark: Deep grading capabilities and marker optimization at scale. Best for brands producing high volumes where a 2% improvement in marker yield saves thousands in fabric costs.

Lectra Modaris: Advanced pattern logic with strong fashion-specific workflows. Integrates well with Lectra’s cutting and spreading equipment if you’re vertically integrated.

TUKAcad: Accessible subscription pricing for small teams moving off spreadsheets or manual pattern work. Good entry point if you’re bringing grading in-house for the first time.

Use case: Grading errors show up as fit complaints after production starts. If you’re catching grading issues in samples, pattern CAD should be your first investment before 3D or PLM.

Tech packs and product development

Before PLM, you need structured specs. Clear tech packs collapse email threads, reduce supplier rework, and make onboarding new manufacturers predictable.

Techpacker: Real-time tech packs with BOM (bill of materials), measurements, construction details, and reusable libraries. Suppliers can access a shareable link instead of downloading outdated PDFs from email. Integrates with Illustrator for clean vector imports.

Use case: If you’re managing specs in Excel or Google Docs and your supplier asks “which version?” more than once per season, switch to Techpacker. It’s the lowest-friction upgrade in this entire guide.

Link your tech packs to your garment guides so your team has reference material for construction standards on jeans, jackets, or cargo pants.

PLM for scaling brands

PLM centralizes product data, approvals, supplier collaboration, and compliance. Add it when spreadsheets and shared drives become the slowest part of your process.

Centric: Broad fashion coverage with strong governance features. Built for brands managing multiple product lines, compliance requirements, and complex approval chains. Higher implementation cost but scales well.

Backbone: Designer-friendly interface with a path from product development into wider retail capabilities. Better for brands that want a less enterprise-heavy feeling while still getting structured workflows.

When to add:
When your team includes designers, product developers, sourcing managers, and QC across multiple time zones, and someone’s always working from the wrong version of a file. Until then, a combination of design tools, 3D, pattern CAD, and Techpacker handles most brands up to 25 people.

Example stacks

Use these as starting points. Adjust based on team size, supplier count, and how much grading you own in-house.

Solo to 5 people

Core stack:

When to add pattern CAD:
When you bring grading in-house or need to optimize fabric yield on high-volume core garments like tshirts and hoodies.

Why this works:
You can test designs in 3D, finalize graphics in Illustrator, and send clean specs to suppliers without hiring a full technical team. Most small brands waste money on PLM before they need it.

6 to 25 people

Core stack:

Integration tips:
Export vectors from Illustrator directly into Techpacker. Use your pattern CAD to validate fit before running 3D simulations. Keep fabric specs and garment construction details centralized in Techpacker so everyone references the same source.

When to add PLM:
When you’re managing multiple seasonal collections simultaneously (Spring, Summer, Fall, Winter) and cross-team miscommunication costs more than software licenses.

25+ people

Full stack:

Governance layer:
PLM manages approvals, compliance, supplier onboarding, and audit trails. Your design and technical tools feed into PLM as the single source of truth. Train tool owners in each department and publish a living playbook that documents workflows between systems.

Pro tip:
At this scale, messy data kills productivity faster than missing features. Enforce naming conventions, run quarterly library audits, and assign ownership for each tool category.

One-season pilot plan with KPIs

A pilot turns opinions into evidence. Track the same measures before and after so you can justify expansion or stop early if value isn’t there.

Before the season starts:

  1. Record baseline metrics:
    • Sample rounds per style (last season average)
    • Approval lead time (design to final sign-off)
    • Late fit defects (issues caught after production started)
    • Marker yield percentage (fabric utilization)
    • Supplier rework rate (how often specs are misunderstood)
  2. Install your first tool:
  3. Publish naming conventions on day one:
    • category-style-season-version
    • Share the document with your entire team and suppliers
    • No exceptions
  4. Build a small library:
    • 3-5 digital avatars with your target fit measurements
    • 10-15 fabric swatches with accurate properties (cotton, polyester, denim)
    • Pattern blocks for your pilot category
    • Standard trims (zippers, buttons, care labels)

During the season:

  1. Run one category through the full cycle:
    • Use the tool for every style in that category
    • Track the same KPIs you recorded at baseline
    • Document friction points (software bugs, training gaps, supplier pushback)

After the season:

  1. Measure deltas:
    • Did sample rounds decrease?
    • Did approval time shrink?
    • Did fit defects drop?
    • Did marker yield improve?
  2. Decide next steps:
    • Green lights: Scale to another category or add a complementary tool
    • Yellow lights: Fix training, naming, or workflows before expanding
    • Red lights: Diagnose root cause (wrong tool, bad implementation, or the problem wasn’t actually a bottleneck)
  3. If cross-team pain persists:
    • Scope PLM with Centric or Backbone
    • Run a second pilot season with PLM before committing to a full rollout

Common pitfalls (and fixes)

You don’t fail because the software is bad. You fail because the data, process, or scope is wrong. Fix the root causes below before you scale.

Buying PLM too early

The mistake:
Small teams buy enterprise PLM because it sounds professional, then spend six months on implementation while their actual design work stalls.

The fix:
Run Techpacker plus your design and pattern CAD tools until cross-functional friction becomes more expensive than PLM licensing and change management. For most brands under 15 people, that threshold never arrives.

Skipping a pilot

The mistake:
Rolling out CLO 3D across all garment categories and seasons at once, then wondering why adoption is inconsistent and results are unclear.

The fix:
One category (tshirts, jeans, jackets), one season, clear KPIs. Prove ROI on a small scale before expanding. If you can’t show improvement on 10 styles, you won’t see it on 100.

Messy libraries

The mistake:
No naming conventions, files saved wherever, duplicate avatars with slightly different measurements, and nobody knows which fabric swatch is current.

The fix:
Enforce naming (category-style-season-version) from day one, assign one person as library owner, and run monthly reviews. Delete outdated files instead of letting them pile up. If your CLO-SET or shared drive looks like chaos, your tools can’t help you.

Under-spec’d hardware

The mistake:
Buying Browzwear VStitcher licenses but running them on laptops with integrated graphics. Simulations crash, rendering takes 20 minutes, and your team stops using the software.

The fix:
Check vendor hardware requirements before buying licenses. 3D tools need dedicated GPUs, 16GB+ RAM, and fast processors. Pattern CAD is lighter but still benefits from proper workstations. Budget for hardware when you budget for software.

No structured training

The mistake:
Assuming your team will figure out Adobe Illustrator or Gerber AccuMark by clicking around. Three months later, everyone’s still doing things the old way.

The fix:
Assign tool owners for each category (design, pattern, 3D, specs). Use official training resources like Browzwear University for structured onboarding. Publish a living playbook that documents your specific workflows, naming conventions, and integration points. Update it every quarter.

Start with one tool, one season, and proof

Most clothing brands buy too many tools too fast and never measure whether they solve real problems. You now have a framework to avoid that.

Pick the bottleneck that costs you the most time or money. Choose one tool that attacks it. Run a pilot on one category for one season. Measure before and after. Scale only when you see green lights.

Your tech stack should make work faster and clearer, not add complexity. If a tool doesn’t deliver measurable value in one season, either fix how you’re using it or stop paying for it.

Start small, measure everything, and build your stack one proven layer at a time.

Frequently Asked Questions

Do I still need Illustrator if I use a 3D tool?

Yes. Adobe Illustrator handles vectors for flats, trims, print designs, and brand assets like logos and hangtags. 3D tools like CLO 3D simulate garments, but they don’t replace your need for clean vector files.

Illustrator integrates cleanly with Techpacker and PLM systems, which makes hand-offs to suppliers predictable. Even if you start graphic designs in Canva or Procreate, finalize production files in Illustrator.

For more on creating strong designs, see our guide on designing for clothing brands.

When should a brand adopt PLM?

When multiple teams, suppliers, and seasonal collections create more friction than your current tools can handle. Specifically:

  • You’re managing 5+ suppliers across different countries
  • Designers, product developers, and sourcing teams step on each other’s work
  • Compliance and approvals need audit trails
  • Spreadsheets cause more problems than they solve

Until then, a stack of design tools (Illustrator, Photoshop), 3D (CLO 3D or VStitcher), pattern CAD (AccuMark, Modaris, or TUKAcad), and Techpacker handles most brands up to 25 people.

Evaluate Centric or Backbone only after you’ve proven ROI on lighter tools.

What’s a pragmatic starter stack?

For most brands starting out:

Design: Adobe Illustrator for vectors, Canva for quick mockups
3D: CLO 3D or Browzwear VStitcher
Specs: Techpacker

Add pattern CAD (Gerber AccuMark, Lectra Modaris, or TUKAcad) when you bring grading in-house or need to optimize fabric yield on high-volume core garments.

Add PLM (Centric or Backbone) when governance and cross-team coordination become bigger bottlenecks than sample rounds or spec errors.

Should I start with free tools like Canva?

It depends on what you’re creating.

Use Canva for:

Use Illustrator for:

Canva is fine for testing ideas, but you’ll eventually need Adobe Illustrator for files that manufacturers can actually use. Start with Canva if budget is tight, but plan the switch to Illustrator before you send specs to production.
