A practical CLO workflow for body data and digital garments
- Use measurement-led drafting to start a pattern from a body’s measurements or a flat sketch.
- Keep made-to-measure adjustments distinct from grading a style across a size range.
- Use CLO’s 2D pattern tools, 3D simulation, and fit maps to review a garment as it develops.
- Validate the digital result against the intended fabric and construction before treating it as production-ready.
For a digital fashion studio, the important question is how body measurements, pattern decisions, and garment review fit together. Made-to-measure (MTM) changes a pattern for one person’s body measurements; grading applies rules to a base pattern to create a size range. The work can connect, but the two processes have different goals. CLO brings pattern drafting and 3D garment review into a fashion-focused workflow, while fit rules and final validation still depend on the team’s design and production decisions.

1. MTM and grading start from different pattern questions
Grading asks how an approved style should change across a standard size range. MTM asks how a pattern should change for one person’s measurement set. Both processes can draw on a shared base pattern, but they should be checked against their own intended outcomes.
A study published in the Journal of Textile and Apparel, Technology and Management illustrates the distinction with a trouser pattern. The researchers began with a size-8 basic pattern, set grading values at selected pattern points for standard sizes, and separately created an MTM pattern using a size table that included standard measurements and an individual customer’s measurements. The MTM example considered waist, hip, thigh, knee, ankle, inseam, and rise. The NC State MTM pattern study shows how a custom pattern can be developed from a base without treating the result as simply another graded size.
A 2023 apparel-pattern study describes traditional grading as using basic or graded patterns with sizing and alteration tables to adjust for a person’s measurements. It also notes that a grading pattern based on average measurements may not suit people who are taller, shorter, thinner, or larger than average. The 2023 study on individualized garment pattern generation reinforces a useful principle: grade rules should be evaluated across the intended size range, while an MTM workflow needs a reliable way to translate individual measurements into pattern changes.
If a studio needs both outcomes, assess them separately. Check whether the graded nest follows the intended size rules, then check whether an individual measurement record changes the pattern in the areas that wearer’s fit requires.
2. Put clear measurement and fit logic behind the pattern
Digital tools are most useful when the team has a clear view of which measurements matter, how they are taken, and what fit each design is meant to achieve. For a trouser, that might include waist, hip, thigh, knee, ankle, inseam, and rise. Another garment will call for its own set of relevant measurements.
Before drafting, record the measurement method and units, the ease target, and the style assumptions. A waist or hip measurement alone does not describe the full fit of a garment, and identical numbers can be interpreted differently if measurement points or procedures are inconsistent. A shared measurement brief gives designers and reviewers a more dependable basis for decisions.
The same care applies to pattern relationships. A team can define which measurements should influence which pattern areas, then use CLO’s measurement-led drafting and editing tools to develop the pieces. Pattern decisions still need informed review: measurement inputs guide the process, but they do not replace knowledge of the garment, its construction, or the fit the design is intended to deliver.
For repeat styles, keep the measurement definitions, pattern changes, and review notes together. That record makes it easier to understand why a pattern changed and to apply the team’s fit intent consistently across later iterations.
3. Make measurement-led pattern development part of the design process
CLO supports pattern development from measurement points as well as flat sketches. Its Pattern Drafter guide describes creating a pattern from those inputs, adjusting measurements, and editing a parametric pattern while retaining its original parameters. It also documents adding grading sizes and entering measurements or grading increments for those sizes.
That range of functions makes CLO useful for more than presenting a finished 3D concept. A designer can begin with a measurement-led pattern, revise its dimensions, and carry the developing pieces into a 3D garment review. When the task is a size range, the grading workflow can be considered alongside the base pattern rather than treated as a separate design problem.
The team remains responsible for choosing sound measurement inputs and checking the result. A parametric relationship only reflects the logic built into it; it does not automatically establish that a style is comfortable, production-ready, or right for every body. Start with a defined fit brief, then use pattern and garment review to see whether the design is meeting it.
For teams building a repeatable process, document which measurements drive important pattern changes and how those changes are reviewed. That work helps turn individual design decisions into a clearer, more consistent studio practice.
4. Bring pattern drafting and 3D review together in CLO
CLO is designed for fashion work that connects 2D pattern development with 3D garment design and review. Its Pattern Drafter guide says users can start from measurement points or flat sketches. The CLO features page describes parametric patterns based on avatar measurements, alongside pattern details such as pockets and hoods.
The value for a design studio is continuity. Pattern pieces can be created or edited in 2D, then reviewed on an avatar in 3D as the garment develops. That lets the team look at silhouette and construction in context and make informed revisions without separating pattern work from visual design review.
CLO’s fit maps add another useful view of the simulated garment. The official guide to Garment Fit Maps describes views for garment tightness, stretch, stress, and pressure. Used together with visual inspection, fit maps can help a team identify areas to examine more closely. They are diagnostic views of a simulation, not a guarantee of wear comfort or a substitute for checking a garment in its intended fabric.
This workflow is especially relevant when a studio wants pattern development and 3D review to inform one another. Designers can inspect how a developing garment looks, use the available map views as additional cues, and revise the pattern as the design evolves. The result is a more connected way to discuss fit and design intent across the team.
5. Treat custom-fit output as a garment-specific deliverable
A custom-fit pattern is only one part of a successful garment outcome. A studio also needs a clear design brief, reliable body measurements, agreed ease and style details, and a plan for reviewing the pattern and finished garment. Without those pieces, a pattern can reflect the numbers entered while still missing the intended fit or production requirements.
For a one-off garment or an early fit sample, keep the deliverable specific: record the wearer’s measurements, selected style details, ease assumptions, file format, and any production notes needed for the next step. In CLO, the team can develop the 2D pattern and review the simulated garment together, then refine the work based on what the review reveals.
A digital review is particularly helpful for discussing proportion and visible design changes early. It can make the design easier to evaluate before a physical sample is prepared, but the intended fabric and construction still matter. A sewn sample remains important when the team needs to assess how the garment behaves on a wearer.
For recurring styles, use the lessons from individual trials to strengthen the studio’s fit brief and pattern library. Keep what the team learns about measurements, ease, and adjustments so the next version starts with a more informed foundation.
6. Run a controlled garment trial before standardizing
Use one garment style and the same body-measurement records to evaluate the workflow. Trousers make a useful test because the NC State study describes pattern development using waist, hip, thigh, knee, ankle, inseam, and rise. Together, those measurements give the team a broader basis for reviewing fit than waist and length alone.
The study’s example used a reference size and an individual customer’s measurements. Apply the same discipline to a studio trial: define one reference fit, measure each test wearer consistently, and keep ease and style settings fixed. For an initial review, include a base-size body, a person with a longer or shorter rise or inseam, and a person whose waist-to-hip proportions differ from the base.
Trial checklist
- Keep one garment design. Hold the design, fabric assumptions, seam allowance rules, and ease target constant throughout the trial.
- Record the measurements. For trousers, record waist, hip, thigh, knee, ankle, inseam (inside-leg length), and rise (the distance from waist to crotch). Note the units and how each measurement was taken.
- Review both pattern tasks. Check a graded size range against its intended rules and an individual pattern against the wearer’s measurements and fit brief.
- Check the pattern file. Review piece count, seam alignment, matching marks, fabric-direction markings, and print scale; confirm the file is ready for the next production step.
- Review the garment. In 3D, inspect the silhouette and areas where the garment pulls or folds, and use fit maps as additional visual cues. In a sewn sample, check ease and movement in the intended fabric.
- Record the work involved. Note the time and people needed to prepare measurements, draft and revise patterns, review results, and prepare files.
CLO gives a studio a connected setting for measurement-led pattern work, grading, and 3D garment review. The trial helps the team see how well its own measurement definitions, design decisions, and review process make use of those capabilities. A consistent record of the fit brief, pattern changes, and review findings will make it easier to improve the workflow and carry learning forward into repeat styles.
FAQ
Can one grading system also support made-to-measure patterns?
Yes. The NC State study starts from a basic trouser pattern and describes both a standard graded size table and a custom measurement table. It treats grading and individual measurement adjustments as related pattern tasks with distinct outputs. CLO’s Pattern Drafter guide also documents grading and measurement-led pattern development; teams should assess each result against its own fit goal.
Does a digital 3D garment review replace a physical fit sample?
No. Use 3D review to assess the developing garment in the studio’s digital workflow and to guide pattern revisions. A physical sample is still important when the team needs to assess how the intended fabric and construction behave on a wearer.
Can a team use more than one kind of review?
Yes. Pattern review, 3D simulation, fit maps, and a sewn sample can contribute different information. Keep a shared record of body measurements, ease assumptions, pattern changes, and review notes so each step refers to the same fit brief.
