A fashion flat is the first time your product looks like itself. Clean 2D sketches with colored flat renderings that show the garment from every angle — front, back, side, construction details — rendered the way a factory will read them.
Before flats, the product lives inside your head. After flats, anyone outside it can see what you're building. That shift matters more than founders expect: it's what makes the difference between "I think we should make this" and "here is what we're making."
What it includes
A complete flat package shows the product in real colorways, with every relevant view (front, back, side, interior if needed) and callouts for any construction detail that won't read from the silhouette alone — pockets, plackets, trims, stitching.
Why it matters
Flats are the bridge between mood and tech pack. Skip them and the tech pack lacks visual reference; the factory makes its own assumptions. Done well, they save sample rounds and protect the design intent through the entire production handoff.
