PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a heavy-weight knit sweater (likely cotton or wool blend) with a distinct waffle or textured weave. Unlike the user's current thin cotton t-shirt, this material has high structural integrity and thickness. It has low specular reflection (matte finish) but requires high normal mapping to capture the depth of the knit texture and the ribbed cuffs/hem. - **Key Features:** - The large, multi-colored "Teddy Bear" graphic patch on the center chest must be preserved with its specific embroidery/chenille texture. - Thick ribbed collar, cuffs, and hemline. - Drop-shoulder seam construction. - The brown earth-tone colorway. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the user's leaning pose and crossed arms: - **Torso:** The sweater is thicker and looser than the current t-shirt; it should add slight volumetric bulk to the user's silhouette, not cling tightly to the skin. The fabric must flatten slightly against the back where the user leans against the pillar. - **Left Arm (crossed):** Significant fabric bunching and folding must occur at the inner elbow and across the forearm. The sleeve must look compressed under the user's arm weight against the torso. - **The Graphic:** The Teddy Bear graphic will likely be partially distorted or folded where the left arm crosses the torso. It must wrap around the curvature of the chest, not sit flat like a 2D sticker. - **Occlusion Handling:** - **CRITICAL:** The user's left hand and the silver wrist watch are positioned directly over the midsection. The sweater must be rendered *behind* the hand and watch. - The user's beard interacts closely with the neckline; ensure the collar sits naturally below the chin without clipping the facial hair. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is in an indoor environment with warm, top-down artificial lighting (yellow/amber tint) and strong reflections from the glossy floor. The studio-lit (cool/neutral) brown sweater must be warmed up to match this ambient temperature. Shadows must appear under the pectoral muscles and inside fabric folds, consistent with the overhead light source. - **Color Calibration:** Apply a warm color grading curve to the sweater to harmonize with the beige/gold tones of the wall and floor. The white parts of the Teddy Bear graphic must reflect the warm ambient light (appearing slightly cream/yellow) rather than stark white. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute freeze on the user’s face, beard, ears, and hairstyle. The neckline mask must be precise to avoid "floating head" artifacts. - **Body Integrity:** Strictly forbidden to slim the user. The simulation must respect the user's existing shoulder width and torso mass. The resulting silhouette should be wider than the original image due to the transition from a thin t-shirt to a thick knit sweater.
