How to Create an AI Lookbook From a Sketch, Tech Pack or Garment Photo

Short answer: Start from the most accurate input you have. A garment photo gives the most faithful result, a tech pack gives exact details to describe, and a sketch is best for early concepts. Convert the input to a clean product image first, then place it on one consistent model in one consistent set.

Who this is for: Designers and brand teams who have designs but no photoshoot yet.

The workflow

1. Clean product image — render the sketch with Sketch to Render, or photograph the sample flat on a plain background.
2. Write the garment description once — fabric, colour, closures, length, print. Reuse it word for word.
3. Fix the model — build a reference set (front, three-quarter, profile).
4. Fix the set and light — one direction for the whole lookbook.
5. Generate look by look — change only the garment.
6. Check every detail against the original design.

Which starting point

Input	Accuracy	Best stage
Sketch	Low–medium	Early concept, line review
Tech pack	Medium–high	Pre-sample sell-in
Garment photo	Highest	Pre-launch campaign, e-commerce tests

Best for / not ideal for

	Use it for	Not ideal for
Sketch input	Fast concept direction	Final product images
Garment photo input	Campaign and social visuals	Measured fit

Questions

Can I make a lookbook without samples? Yes, from sketches or tech packs, but treat it as a concept until a sample confirms the design.

What causes details to change? Vague descriptions and long prompts. Reuse one precise garment description.

Do I need special software? No. A sketch-to-render tool, an image model and a consistency method are enough.
