Key takeaways
- A clear digital workflow: Academic analysis in Virtual Fit vs. Physical Fit describes four stages in digital garment development: design, preparation, simulation, and rendering. CLO brings pattern development and garment simulation together in a practical environment for working through these stages.
- Digital and physical review work best together: 3D simulation can help teams assess a garment early, but it does not replace every physical fitting. Research identifies ongoing challenges in representing fabric mechanics and deformation, so physical checks remain important for final fit and feel.
- Fabric inputs affect results: A study indexed in PMC found that digital prototypes simulated with mechanical values from systems such as KES-FB showed higher deformation than physical garments, with more symmetry between the left and right sides.
- Digital workflows are part of a wider shift: McKinsey & Company reports that larger apparel suppliers are pursuing digitization and automation. More than 35 percent of fashion and luxury executives surveyed said they were deploying generative AI in select functions for routine tasks.
- Remote review has a practical role: Grand View Research points to demand for better visual information and remote collaboration as drivers of visual and extended reality technologies.
Virtual sampling and digital fit validation
Virtual sampling gives apparel teams a way to review pattern geometry, ease, and early drape before committing materials and time to physical samples. In a 3D workflow, edits to a 2D pattern can be reviewed on a simulated avatar, helping teams iterate on design intent and fit earlier in development.

Digital simulation stages and mechanical variables
Research presented in Virtual Fit vs. Physical Fit describes four primary steps in digital sampling:
- Design
- Preparation
- Simulation
- Rendering
Digital prototypes are valuable for reviewing a garment, but they do not reproduce every aspect of real textile behavior. As Virtual Fit vs. Physical Fit notes, virtual simulation cannot yet replace physical fitting in every situation. A study of woven fabric mechanics indexed in PMC found that digital prototypes simulated with mechanical parameters from the KES-FB system showed higher deformation than physical prototypes. The researchers also observed pronounced left-right symmetry in the deformation of the digital garments. These findings are a useful reminder that material data and physical checks both matter when making fit decisions.
Defining digital versus physical sample decision criteria
A thoughtful workflow uses digital review where it is most useful and keeps physical verification for questions that depend on real materials, movement, or construction. Since virtual simulation does not resolve every technical fit issue (Virtual Fit vs. Physical Fit), teams can use the two methods to complement each other:
- Digital review: Assess silhouette, early drape, graphic proportions, and grading across sizes.
- Physical verification: Check final construction and fit, feel the material, and validate wear where simulation alone cannot answer the question.
CLO supports this review process with tools such as fit maps and Softbody Simulation, which help teams visualize fabric tension, contact, and movement. These views can make a 3D review more informative, while physical samples remain the right choice for final tactile assessment and fit verification where needed.
Asynchronous 3D review and multi-stakeholder approval routing
Garment development often brings together design studios, pattern rooms, buying teams, and manufacturing partners. A shared digital process makes it easier for people in different roles and locations to review the same design and communicate changes. Grand View Research identifies demand for richer visual information and remote collaboration as drivers of visual and extended reality technologies.

Organizing multi-stakeholder feedback loops
A digital product review can bring together feedback from technical designers, pattern makers, merchandisers, and suppliers, with each group focusing on the details most relevant to its work:
- Pattern makers and technical developers: Draft and edit 2D patterns, check points of measure (POM), adjust grading, and review garment drape and fit maps.
- Designers and merchandisers: Review silhouette, colorways, graphic placement, and the visual details of a collection.
- Production and manufacturing partners: Check assembly details, notch alignment, BOM data, and production exports such as DXF, AI, and vector PDF.
Clear file organization and revision practices help teams avoid confusion as a style develops. CLO is the design and garment simulation environment; CLO-SET complements it with a dedicated place to organize files, share 3D assets, and coordinate product-development reviews. Used together, they help teams keep design work and collaborative review connected while maintaining a clear process for changes to master pattern files.
Mitigating revision bottlenecks
According to The State of Fashion, larger apparel suppliers are pursuing footprint optimization, digitization, and automation, while smaller players face growing pressure. The report also notes that more than 35 percent of fashion and luxury executives surveyed said they were deploying generative AI in select functions for routine tasks such as image creation and product discovery. For apparel teams, thoughtful review milestones and well-defined processes can make it easier to share design intent and keep feedback moving across locations.
High-fidelity visual asset generation and colorway pipelines
After teams have reviewed garment geometry and initial fit, the 3D garment can move into visual development. Fabric textures, lighting, avatar poses, and material finishes all contribute to a clear and compelling presentation of the design.

Material definition and structural textures
Good material definition helps a digital garment communicate its surface and construction. Common parts of a 3D apparel visualization workflow include:
- PBR material maps: Use physically based rendering maps and supported naming conventions to define surface appearance.
- Texture editing and blending: Combine texture layers and blend graphic prints with fabric textures in Texture Editor.
- Fabric digitization and material data: Work with digitized fabric properties through CLOFAB and the enterprise CLO zFab Kit, which includes Cutter, Draper, and Scanner devices.
CLO includes tools for working with detailed materials and finishes. The Knit Swatch Editor supports adjustments to knit gauge, courses, wales, and yarn thickness, while interoperability with systems such as SHIMA SEIKI ApexFiz can connect apparel workflows. CLO also offers ways to create distinctive surfaces, including denim wash effects and fur, directly in the 3D authoring environment.
Colorway management and batch rendering
Seasonal collections often need to be shown in multiple color and material options. Colorway tools make it possible to explore palettes, fabrics, and prints on the same garment model, without rebuilding the pattern for each SKU.
- Pattern and simulation review: Check drape, avatar movement, and trim placement.
- Colorway setup: Select options and edit buttons, fabrics, topstitching, and print layouts in Colorway Editor.
- Lighting and camera setup: Name render lights, adjust depth of field by custom view, and set snapshot preferences.
- Rendering and export: Create high-resolution snapshots up to 8K in the 3D window, save ZPAC files with 3D/2D display settings, or export formats including glTF with avatar animations, USD/USDZ, and OBJ.
Digital showroom creation and wholesale buyer presentations
Digital presentations give apparel teams another way to share collections with buyers, retail partners, and other commercial stakeholders. CLO can help teams develop polished 3D garment visuals, while CLO-SET provides a connected space to share and review those assets. Grand View Research points to demand for richer visual information and remote collaboration as drivers of visual technologies and virtual presentations.

Structuring digital presentations and review assets
A useful digital presentation brings garment visuals together with the information a buyer or product team needs to review:
- Interactive 3D viewing: Share turntable views and animated avatar garments to communicate silhouette and movement.
- Colorway and material visualization: Show color options, textures, and wash finishes without cutting additional sample yardage for each visual review.
- Connected collaboration: Use CLO-SET alongside CLO to share virtual prototypes, gather feedback, and present collections remotely.
- Technical and production information: Connect visuals with BOM data, points of measure (POM), and 2D pattern information for downstream review.
Presentation workflows for distributed teams
Product and commercial teams can choose a presentation approach that suits the review:
- Interactive walkthroughs: Use virtual samples and 360-degree renders in live meetings to discuss styling and fit intent.
- Asynchronous platform review: Share 3D visuals and snapshots through collaboration platforms so partners in different time zones can review styles when convenient.
- Hybrid evaluation: Review silhouette, styling, and colorways digitally, and use physical fabric swatches when buyers need to assess material by touch.
Operational lead times, adoption realities, and industry benchmarks
Digital sampling and presentation affect several steps in an apparel development calendar. The exact business impact will vary by team and workflow, so it is useful to distinguish broader industry reporting from academic findings and individual company results.

Implementation caveats and technical challenges
Digital tools can make product development more visual and collaborative, but teams should plan for a few practical considerations:
- Digital fitting has limits: Research in Virtual Fit vs. Physical Fit explains that 3D simulation cannot eliminate every physical fit session; modeling complex fabric mechanics and body movement remains challenging.
- Organizational change matters: The State of Fashion notes that technological transformation calls for redesigned processes and technical talent, while preserving creative design work.
- Hardware and skills: High-quality simulation, pattern digitization, and rendering call for suitable workstation hardware and training for pattern makers and technical design teams.
CLO and CLO-SET can support a connected digital process, but a successful rollout also depends on choosing appropriate review points, building team confidence, and keeping physical checks where they are needed.
