PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment appears to be a standard cotton jersey blend. It is a matte fabric with low reflectivity and high flexibility. It should exhibit soft, rolling folds rather than sharp creases. The simulation must replicate a medium-light weight, allowing for slight cling to the pectoral muscles but hanging loosely around the midsection. - **Key Features:** The white ringer trim (binding) around the neckline and armholes is a structural boundary that must remain distinct. The "NORTH CAROLINA 88" graphic features a distressed, vintage screen-print texture; this texture must be preserved and mapped correctly across the curvature of the chest. The bottom hem stitching must be visible. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The target user has an athletic build with broad shoulders. The source garment is a ringer tank, likely tighter at the neck than the user's current loose black tank. The simulation must fit the shoulder straps of the red tank to the user's trapezius muscles. Due to the raised right arm (holding the phone), the fabric should pull slightly taut across the right pectoral and bunch moderately in the right armpit area. The left side should hang relatively straight with gravity. - **Occlusion Handling:** The user's right hand and the smartphone are significant occlusions positioned directly over the center-chest area. The "NORTH CAROLINA" graphic will be partially obscured by the hand and phone. These elements, along with the bracelet on the right wrist, must be segmented and layered *over* the generated red garment. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment is an indoor room with dim, top-down, diffuse artificial lighting (likely warm tungsten), creating soft shadows under the jaw and arms. There is significant mirror haze and surface smudge/glare overlaying the entire image. The bright, flat daylight lighting of the source cloth must be dimmed and diffused to match this low-light environment. - **Color Calibration:** The source red is too vibrant for the target scene. It must be desaturated and shifted slightly warmer/darker to blend with the room's ambient occlusion. The white trim must be tone-mapped to a duller off-white/light grey to match the white wardrobe door's luminance in the background, ensuring it doesn't glow unnaturally. The mirror's "dirty" texture layer must be applied on top of the final render. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's face, facial hair (beard/stubble), hairstyle, and neck anatomy must remain completely frozen. The skin tone on the arms and neck must not be altered by color bleed from the red shirt. - **Body Integrity:** The user's deltoids and bicep definition must be preserved. The simulation must strictly adhere to the user's current torso volume; do not slim the waist or artificially bulk the chest. The transition from the shirt hem to the grey sweatpants must look natural without warping the waistband of the pants.
