### Best for

Building and releasing a tech pack without silent defaults, duplicate sources, or ambiguous final files

### What the source establishes

The guide cites published ISO documented-information, garment-measurement, stitch, and seam sources plus current U.S. FTC textile and care-labeling guidance; it discloses ISO 10013:2021's current review stage, and its working record makes organization-specific requirements, suppliers, evidence, issues, and approvals explicit.

### Know before using

The record does not create product specifications, prove fit or manufacturability, select materials or construction settings, establish legal compliance, reproduce licensed standards, or replace qualified technical, production, quality, testing, sourcing, logistics, safety, compliance, and legal review.

## 2. PatternLab London

- Area: Patterns & fit
- For: Both
- Location or jurisdiction: Global
- Access: Paid
- Format: Software

- Linked page reviewed: 2026-07-21

### Best for

Generating an editable custom-measurement block

### What the source establishes

PatternLab London's current drafting page says a user creates a measurement profile, selects a basic block or sloper, adjusts fit, dart placement, length, seam allowance, and sleeve options, then downloads the generated result as tiled PDF, AI, or SVG. The live catalogue names bodice, dress, trouser, and stretch blocks and displays a price before purchase.

### Know before using

A measurement-generated draft is a starting block, not independent evidence of body capture, comfort, mobility, balance, garment ease, or production fit. The result depends on measurement accuracy, supported ranges, formula assumptions, selected options, and output handling. Review the service's privacy terms before storing body data and sew a representative toile before design, grading, or production use.

## 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.
