CLO for Fashion Design: 2D Patterns, 3D Garments, and Virtual Sampling
See how CLO connects fashion patternmaking, 3D garment simulation, and virtual sampling, with CLO-SET supporting collaboration and product development.
Key takeaways
- Built around apparel development: CLO connects 2D pattern creation and editing with 3D garment simulation.
- A practical design-to-review workflow: Teams can develop patterns, review garments virtually, and prepare production-oriented pattern, measurement, and BOM data where supported.
- CLO-SET complements CLO: CLO is the garment design and simulation environment; CLO-SET is a separate collaboration and product-development platform.
- Virtual samples support decisions, not guarantees: Review the garment and its inputs carefully, and use physical checks when material, fit, movement, or construction questions remain.
What CLO brings to fashion product development
A promising fashion design still has to work as a pattern, fit a body, and behave as intended in fabric. CLO brings 2D pattern creation and editing together with 3D garment simulation, giving fashion designers, pattern makers, and product teams a way to review those decisions in context.
Virtual sampling can help teams spot questions earlier and share design intent more clearly. It does not guarantee a perfect physical result or remove the need for physical checks in every workflow. The most useful results come from careful pattern, avatar, and fabric inputs, followed by practical review.
CLO is built for fashion and apparel development. Marvelous Designer is its sibling software, aimed at digital garments for animation and gaming. The products share garment-simulation technology, but serve different workflows.
How CLO supports the development process
Develop patterns and review garments in 3D
CLO supports 2D pattern creation and editing alongside 3D garment simulation. Pattern Drafter, points-of-measure tools, and grading controls support pattern development and measurement work. Teams can evaluate the resulting garment in 3D as they refine a design.
CLO also supports production-oriented workflows involving pattern, measurement, and BOM data where the relevant feature supports the task. For file exchange, review the current CLO pattern import and export guidance and validate the receiving workflow before using exported files for production.
Simulate fabric and evaluate fit
CLO simulates garments on avatars using patterns and fabric properties. Teams can review silhouette, fit, drape, and garment details during virtual sampling. Keep material inputs and fit expectations in view: simulation is a tool for evaluating a digital garment, not an independent guarantee of physical fit.
A published study has examined CLO garment simulation against physical prototypes under defined test conditions. That kind of research can inform a team's evaluation, but a result from one study should not be treated as a universal accuracy rating across fabrics, garments, and workflows.
Explore ideas and prepare visuals
CLO includes documented AI tools such as AI Studio, AI Pose Generator, AI Pattern Drafter, and Sketch on Avatar. These can support selected creative and drafting tasks, while designers retain control over review and refinement. Treat generated or drafted work as a starting point to inspect, not as production-ready output without technical checks.
After building and simulating a garment, teams can review its appearance and prepare visuals for development discussions or presentations. A render can communicate design intent; it does not on its own confirm manufacturing readiness or physical performance.
Share work with CLO-SET
CLO-SET is a separate collaboration and product-development platform that can be used alongside CLO for review, collaboration, and presentation workflows. In practical terms, CLO supports garment design and simulation, while CLO-SET can help teams organize and share work for review.
Before rolling out a shared review process, agree on who can view or edit files, how feedback is recorded, and which approved files move to the next development step. Confirm the features and permissions available in the CLO-SET setup your team uses.
A practical way to evaluate CLO
A short pilot using one of your own garments can show how CLO fits your team's day-to-day work. Include the people responsible for design, patterns, technical review, and production handoff.
- Choose a representative style: Include the pattern complexity, fabric, trims, and fit questions your team encounters regularly.
- Prepare the inputs: Check the base pattern, measurement chart, avatar, and fabric information before building the virtual garment.
- Build and simulate: Create the garment in CLO and note which design and fit decisions are easier to review in 3D.
- Review the size range: Apply your team's grading approach and check the measurements and garment result across the intended sizes.
- Test the handoff: Export a sample file and verify it in the destination workflow before relying on it for production.
- Share feedback: Use CLO-SET where it suits your review process, and agree on how comments and approvals will be recorded.
- Check what still needs a physical test: Use physical samples to resolve any remaining questions about material behavior, movement, construction, or approval requirements.
The goal is not to force every task into a digital workflow. It is to see where CLO helps your team make and communicate better decisions, and where a physical check remains the right next step.
Frequently asked questions
Is CLO designed for fashion apparel work?
Yes. CLO is a 3D fashion design and garment-development application for creating and editing 2D patterns, simulating garments on avatars, and supporting virtual sampling. Marvelous Designer is its sibling product, oriented toward digital garments for animation and gaming.
Can CLO replace every physical fit sample?
No. Virtual review can help teams examine pattern, proportion, and assembly questions before cutting a sample, but it cannot guarantee a physical result. Keep physical checks for unresolved material, fit, movement, construction, and approval questions.
Is CLO-SET part of CLO?
No. CLO-SET is a separate product that can support collaboration and product-development workflows alongside CLO.
Does CLO support production-oriented pattern work?
CLO supports pattern creation and editing, grading and measurement workflows, and production-oriented pattern, measurement, and BOM data where the relevant feature supports the task. Check the current documentation and test file exchange with the receiving system.
What is the difference between CLO and Marvelous Designer?
They are sibling products that share garment-simulation technology. CLO is oriented toward fashion and apparel development, while Marvelous Designer is oriented toward digital garments for animation and gaming.
