PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a heavyweight cotton-blend fleece or jersey. It is matte with low specularity and significant thickness. Unlike the user's current thin textured top, the hoodie simulates a semi-rigid structure that resists micro-folding but creates larger, softer accumulation folds. Light absorption is high; it should not shine. - **Key Features:** The silver central zipper, white drawstrings with metal aglets, kangaroo pockets on the lower front, and thick ribbed cuffs and bottom hem are critical details. The hood structure resting at the nape of the neck must be preserved in 3D volume, not flattened. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The hoodie has a relaxed fit compared to the user's current fitted red top. It must not cling to the waist; instead, it should hang vertically from the bust line, creating a "blousing" effect just above the hips where the ribbed hem sits. The sleeves must exhibit compression wrinkling at the inner elbow and bunching at the wrist, as the ribbed cuffs will arrest the fabric flow before the hand. - **Occlusion Handling:** The user has short hair, so shoulder occlusion is minimal. However, the user is wearing a watch on the left wrist; if the hoodie sleeves are long, they naturally cover the watch. If the sleeves are pulled up, the watch must be layered *over* the cuff. The user's hands are free and hang by the side; the sleeves must drape around the wrist anatomy without intersecting the thumb or fingers. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment is an overcast outdoor setting with soft, diffuse global illumination. There is no harsh direct sunlight. The studio highlights present on the source image (top-down harsh white light) must be neutralized and replaced with soft, cool-toned ambient skylight. Shadows should be contact-based (ambient occlusion) rather than directional cast shadows. - **Color Calibration:** The deep navy of the hoodie must be desaturated slightly to match the outdoor atmospheric perspective. The white drawstrings must be tone-shifted from "studio white" to a cooler, slightly greyish white to match the ambient temperature of the cloudy sky. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's entire head, including the short hairstyle, sunglasses, nose, mouth, and jawline, must remain absolutely frozen. The skin tone on the neck and hands must be preserved. - **Body Integrity:** Strict prohibition on body warping or slimming. The user's stance and shoulder width must remain constant. The hoodie adds bulk to the silhouette; do not artificially tuck it in or slim it down to mimic the current red top's silhouette. The jeans and green footwear must remain untouched.
