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
GPT Image 1
- + Excellent replication of the outfit from Image 2, including the specific coat, plaid scarf, watch, and jeans.
- + Near-perfect facial and background consistency compared to Image 1.
- + Realistic lighting and shadows that match the environment of the source image.
Grok Imagine Image Pro
- + Keeps the background and person's head very close to the original source image.
- − Completely ignored the clothing in Image 2, generating a generic royal outfit instead.
- − The hands are a different skin tone than the face, leading to a major anatomical inconsistency.
- − Failed the primary instruction to use the 'exact elaborate outfit' from the reference.
Verdict: GPT Image 1 followed the instructions almost perfectly, successfully transferring the specific pea coat, plaid scarf, and watch from Image 2 while maintaining the identity of the person in Image 1. Grok Imagine Image Pro completely failed the prompt by generating a random royal costume that was not present in any source image and suffered from inconsistent skin tones on the hands.
