| 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. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements. | A factory profile, platform label, bid, estimate, or message does not establish current identity, factory ownership, capability, capacity, workmanship, pricing, compliance, delivery, or project fit. Paid-plan visibility can affect who responds. Verify the production site, subcontracting, references, samples, quality and compliance records, specifications, commercial terms, and remedies directly. |

| 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. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later. | Maker's Row currently lets a brand submit a project before advance sign-up, then provides access to an account. Its project workflow records product details and files and connects projects with factories by location and specialty. Search guidance lists apparel capabilities such as pattern making, sourcing, sample making, and production. Factory access to bids is plan-dependent. |
