PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a medium-weight cotton jersey. It possesses a matte finish with low specularity (no shine). The simulation must account for standard cotton friction; it is soft but holds structure around the neckline and hem. It creates soft, rounded folds rather than sharp creases. - **Key Features:** The central graphic ("THE MISRAGLEN", "NALIEE", and the mountain emblem) must be preserved without distortion. The "muscle tee" cut (deep, sleeveless armholes) and the ribbed crew neckline are structural essentials. The silver chain present on the source model must be removed; only the textile texture should be extracted. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The target user has a broader chest and shoulder build than the source model. The garment must be scaled laterally to accommodate the user's torso width while maintaining the "relaxed/oversized" aesthetic of the tank top. Since the user is currently wearing a sleeved t-shirt, the simulation must generate skin texture for the user's upper arms/deltoids where the new sleeveless cut exposes them. The fabric should hang vertically from the pectorals, minimizing the horizontal tension lines seen in the user's current purple shirt. - **Occlusion Handling:** The user's beard hair overlaps the neckline; the new garment's collar must be rendered *under* the facial hair. The necklace seen on the source garment must be digitally removed so it does not appear on the target. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user's environment has a warm, ambient lighting setup with a strong pink/red color cast bouncing off the background walls. The white fabric of the source garment must not remain studio-white; it must absorb the ambient red/pink diffuse lighting to integrate realistically. Shadows should be soft and diffuse, consistent with the indoor lighting. - **Color Calibration:** A warm temperature shift is required for the white tank top. The black text on the shirt should appear slightly washed out (dark grey-blue) rather than absolute black to match the contrast levels of the user's image. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's jawline, lips, nose, and especially the facial hair (beard/stubble) must remain pixel-perfectly frozen. - **Body Integrity:** The user's natural shoulder width and chest volume must be preserved. The simulation must not warp the user's torso to match the slimmer frame of the source model; the cloth must deform to fit the user, not the reverse.
