How to Keep Seams, Drape and Fabric Texture Accurate in AI Virtual Try-On

Quick answer: AI try-on loses seams and drape when the garment photo is small, wrinkled or shot at an angle, and when the prompt describes the outfit instead of locking it. Use a flat, evenly lit, high-resolution garment photo, name the fabric weight and construction details, tell the model to keep the garment unchanged, and check seams, hems and prints at 100% before you publish.

Why garments change in try-on

The model redraws the garment to fit a new body and pose. Every detail it cannot see clearly, it guesses. Topstitching, pocket placement, button count and the way a heavy wool falls are the first things to drift.

Step by step

1. Shoot the garment flat or on a mannequin, front-on, in soft even light, at least 2000px on the long side.
2. Remove creases and lint; the AI copies wrinkles as if they were design.
3. In the prompt, name the fabric: "heavy 400gsm wool, structured shoulder, double-needle topstitching".
4. Add a lock line: "keep the garment exactly as in the reference: same seams, buttons, pocket position and print scale".
5. Choose a pose that shows the garment: standing, arms slightly away from the body.
6. Zoom to 100% and compare seams, hem length and print alignment to the original.

Prompt to copy

Full-body e-commerce photo of the model wearing the exact garment from the reference. Keep all seams, buttons, pocket positions, hem length and print scale unchanged. Fabric: [weight and fibre], natural drape with soft folds at the waist. Soft studio light, light grey background, 50mm lens.

Common mistakes

• Using a phone photo with the garment folded or hanging crooked.
• Asking for a dramatic pose that hides the construction.
• Describing a different colour name than the real one.

Where to do this in the Lab

• Virtual Try-On — pay as you go, no subscription.
• Creative Workspace — save the garment as a reference and reuse it across shots.
• Claude & ChatGPT workshop — write product briefs that keep details consistent.

FAQ

Why does AI try-on change my garment?

It redraws the garment for a new body and guesses any detail it cannot see clearly in the reference.

What reference photo works best?

A flat, front-on, evenly lit, crease-free photo at high resolution.

Can AI keep a print in the right scale?

Usually, if you say "keep print scale unchanged" and check it at 100%.

Is AI try-on accurate enough for a product page?

It can be, but always compare the result to the real sample before publishing.
