A fashion tech pack (or technical package) is a comprehensive document provided by brands or designers to factories. It details how to make, construct, and assemble garments or fashion products, acting as a blueprint to ensure proper garment production.
Typically used for large-scale production, tech packs include technical drawings, measurements, grading rules, colorways, bill of materials, construction details, costing sheets, and reference images. For smaller production lines, a spec sheet might suffice.
In short, a tech pack fashion contains all necessary information for efficient and accurate garment production at the factory level.
