| Know before using | 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. | An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. | 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. |

| What the source establishes | 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. | The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions. | 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. |
