### Best for

Coordinating an independent sewing-pattern test

### What the source establishes

Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed.

### Know before using

The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer.

## 2. Lectra Modaris

Permanent record: <https://stitchauthority.com/directory/lectra-modaris>
Source page: <https://www.lectra.com/en/fashion/products/modaris>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Apparel brands
- Location or jurisdiction: Global
- Access: Quote-based
- Format: Software
- Source type: First-party platform
- Linked page reviewed: 2026-07-21
- Next review due: 2027-01-17

### Best for

Enterprise pattern rooms and supplier file exchange

### What the source establishes

Lectra's current Modaris page identifies version 2025.2 as the latest listed release and describes a one- to three-year subscription with two releases per year. The modular range covers base-pattern creation and modification, grading and industrialization, native-file supplier work, pattern libraries, synchronized 2D and 3D prototypes, configurable or imported mannequins, and separate conversion and consumption-estimate add-ons.

### Know before using

The page does not publish price and its product-quality, error-prevention, data-loss, and fit statements are vendor claims. Capabilities vary across Essential, Classic, Expert, 3D, and add-ons. Confirm licenses, modules, support, system and file requirements, then pilot approved blocks, grade rules, supplier reopen, material and mannequin data, plot or cut outputs, and risk-appropriate physical fit and production checks.

## 3. Apparel Grade-Rule & Size-Run Validation Record

Permanent record: <https://stitchauthority.com/directory/grading-guide>
Source page: <https://stitchauthority.com/guides/pattern-grading-explained>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Apparel brands
- Location or jurisdiction: Global
- Access: Open access
- Format: Stitch Authority
- Source type: Stitch Authority
- Linked page reviewed: 2026-07-16
- Next review due: 2027-07-16

### Best for

Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence

### What the source establishes

The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments.

### Know before using

The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review.

## Next checks

1. Remove any route whose audience, jurisdiction, access, or scope does not match the job.
2. Open the permanent record and source page for every remaining route.
3. Recheck facts that can change after the listed review date.
4. Verify project-specific capability, terms, test evidence, and legal requirements with the responsible source or provider.
5. Record the reason for the final choice outside Stitch Authority.
