| 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. | The record does not supply universal POM values, validate fit across a population, prove process capability, choose a statistical study or sampling plan, reproduce licensed standards, or replace qualified technical, fit, quality, statistical, safety, compliance, and legal review. | A profile, proposal, match, or escrow status does not establish factory ownership, identity, capacity, workmanship, quality systems, labour or chemical compliance, delivery performance, contract enforceability, or project fit. Verify the legal and production entities, references, site and subcontracting, samples, compliance evidence, specifications, 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 guide cites current ISO, AATCC, and NIST sources for body and garment measurement boundaries, textile conditioning, dimensional-change testing, repeatability and reproducibility, and AQL-indexed sampling, while requiring the live product owner to set rather than inherit numerical tolerances. | Sewport's current brand workflow starts with an account and guided project enquiry, then exposes proposals from garment factories and production specialists. The platform tells brands to compare profiles, portfolios, location, price, and communication, then record service, delivery, payment, and contract terms in a formal proposal. Its service-provider workflow includes factories, sample studios, pattern cutters, tech-pack makers, sourcing specialists, and material suppliers, with optional split-payment escrow. |
