Outfit Transfer Challenge
EditingEdit instruction
“Use Image 1 as the base person. Dress them in the exact elaborate outfit from Image 2 (including all layers, accessories, jewelry, and shoes). Carefully adapt the clothing to the body shape and pose in Image 1 while maintaining realistic fabric behavior, correct proportions, and perfect lighting/shadow matching. Keep the person’s exact face, hair, and background completely unchanged.”

AI Judge Analysis
Nano Banana
- + Successfully preserved the exact face and sand patterns from Image 1
- + Matches the specific scarf pattern and coat style from Image 2 more closely
- − Poorly blended neckline with visible seams around the chin
- − Body proportions are distorted, making the head look too large for the torso
GPT Image 1
- + High visual quality and seamless integration of clothing onto the character
- + Excellent lighting and realistic fabric rendering
- − Significantly changed the person's facial features and hair, failing the 'exact face' instruction
- − Simplified the scarf pattern compared to Image 2
Verdict: Nano Banana followed the specific preservation instructions much better by keeping the original face and vitiligo patterns, though the technical execution of the 'head swap' is jarring. GPT Image 1 produced a much more photorealistic and aesthetically pleasing image, but it failed the primary task requirement by generating a new face and changing the hair instead of preserving the person from Image 1. Nano Banana's strict adherence to identity makes it the winner for this specific editing task despite lower technical polish.
