A tech pack is the document set a factory uses to build your garment accurately: flat sketches, measurements by size, fabric and trim specs, construction notes, and labelling placement.
You do not need a complete tech pack to start. A reference photo or a rough sketch is enough for an initial feasibility conversation — we will tell you what's missing and help fill the gaps as sampling begins. What matters most early on is fit intent, fabric direction, and any construction details you consider non-negotiable.
