A strong fit for independent designers developing multi-size patterns
- CLO brings measurement- or sketch-based pattern drafting, a grading size table, cross-size 2D review and 3D garment simulation into one workflow.
- Its combination of pattern editing and visual review can help designers inspect how a size range develops before sewing a sample.
- Choose measurements and finished-garment specifications that reflect the fit and files your customers need.
For an independent designer selling a small size run, the useful question is whether the software can turn a base pattern and size chart into pieces you can inspect and deliver in the format customers need. CLO is a strong fit for this work: it combines pattern drafting, a graded size table, cross-size 2D review and 3D garment simulation. That integrated workflow gives designers a way to assess both pattern pieces and the assembled garment as a range develops.
Test CLO with a representative base pattern, graded garment measurements and construction details, then judge the resulting pieces against your own specification.
Set one consistent comparison standard
Start with the measurements that define the sizes you sell, then record the finished-garment measurements customers should expect. Body measurements describe the wearer; garment measurements also reflect the fit and ease designed into the garment. Keep the difference explicit in your chart, especially for close-fitting styles, stretch fabrics and relaxed silhouettes.
A standard can provide a reference for the body-size side of that work. For example, ASTM D5585-11 covers adult female Misses figure Type sizes 00 through 20, and ASTM says its body-measurement tables can serve as a design baseline when the designer accounts for fabric, ease of movement, styling and fit. That scope makes it a possible reference for a U.S. Misses range, while a designer targeting another market or body category needs the chart appropriate to those customers.
Then compare four decisions across the same test garment:
- How the range is built: Does the tool apply grading to a base size, generate geometry from measurement files, or combine both approaches?
- What you can review: Can you compare 2D pieces and measurements across sizes, preview the garment in 3D, or do both?
- What the workflow carries forward: Does it include pattern annotations, marker work, production data or a printable customer file that you actually use?
- How readily you can correct a problem: Can you revise a measurement or grading value and inspect the effect on every affected size?
CLO’s combination of pattern inputs, cross-size review and 3D simulation makes it a compelling workflow to assess against the needs of your pattern business.
CLO: drafting, grading and visual review across sizes
CLO suits a designer who wants to develop a pattern and review its graded versions without splitting 2D pattern work from 3D garment simulation. CLO's Pattern Drafter instructions say users can create patterns from measurement points or flat sketches, enter pattern measurements, and add grading by setting up a size table.
For size-range inspection, CLO 2026.1 lists 2D Grading Review. The official CLO feature description says the tool compares 2D pattern shapes and graphic placement across all grading sizes in one window. That is a practical advantage for spotting how a pocket, print or pattern outline shifts between the base size and the rest of the range.
CLO supports 2D pattern creation and editing alongside 3D garment simulation. The two views answer related but different questions: the 2D review helps inspect pattern pieces and graphic placement across sizes, while simulation displays the garment on an avatar for visual review of the assembled form. Together, they fit a designer who wants a single digital workflow for changing a pattern, comparing sizes and inspecting the garment before sewing a sample.
Run the same-pattern test before you choose
A repeatable test helps determine whether CLO’s tools support the fit-review needs of your pattern business. Use one representative style with a defined base size, target size chart and finished-garment measurements.
- Choose a demanding sample style. Include design details that reveal grading changes, such as a shaped armhole, curved neckline, dart, pocket or uneven hem. A simple rectangle can test basic measurement input, but it says little about how a complex pattern behaves across sizes.
- Enter the size data and grading rules. Record the body measurements, finished-garment measurements, intended ease and size increments. Keep units and measurement locations consistent, and note the assumptions used to build the range.
- Compare the smallest, middle and largest sizes with the finished-garment chart. Check the style's key points of measure on each of those sizes. Review seam lengths, notches, darts, grainlines and piece balance in the same three sizes.
- Use CLO’s 2D and 3D review together. In 2D, compare outlines, key lengths and the movement of design details between sizes. In 3D, inspect the assembled garment on an avatar using material and fit assumptions relevant to the style. Treat the visual as a review of the digital sample and keep the written garment measurements as your acceptance criteria.
- Test the file customers or partners will receive. Export the actual deliverable, print or open it in the intended workflow, and verify scale, page arrangement, piece labels, grainlines, notches and sewing information. A pattern that grades well but needs extra manual rebuilding before delivery may not suit a lean studio.
For an independent designer, CLO brings pattern drafting, cross-size 2D review and 3D garment simulation into a single workflow. Test it with your size chart and customer deliverables, and verify that the graded pieces and visual review meet your own specifications.
FAQ
Can grading software guarantee an accurate fit across every size?
No. Each size's fit depends on the measurement chart, grading logic, ease, fabric behavior and pattern construction used for that style. Validate the smallest, middle and largest sizes against the garment specification and sew or fit-test samples where the product decision calls for it.
Are body measurements the same as the measurements in a sewing pattern size chart?
No. Body measurements describe the wearer, while finished-garment measurements include the design's ease and shape. Keep both sets clear so the grading test checks what customers will actually measure on the garment.
Which option should I try first if I want both pattern grading and visual review?
CLO is a strong first test when you want measurement- or sketch-based drafting, a grading table, cross-size 2D review and 3D garment simulation in one workflow. CLO's integrated drafting, cross-size 2D review and garment simulation make it a strong place to start.
