Can a brand start from reference images instead of a complete tech pack?

 Yes, a brand can often start from reference images if the project is still in the ODM or early development stage. Reference images can help define the product direction, but they should be supported by notes on fabric feel, fit target, function, color, branding, and intended use. For OEM production, a more complete tech pack is usually needed because measurements, construction details, trims, and grading expectations must be clearer before bulk planning.
