PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a heavyweight cotton fleece blend. It possesses high structural rigidity compared to the user's current thin synthetic t-shirt. The simulation must reflect a matte surface for the cotton areas, but utilize high specular mapping for the rhinestone/stud detailing on the "Prestige" text to capture light glints. The cuffs and hem are ribbed elastic, requiring a tighter compression radius than the main body. - **Key Features:** 1. The "Prestige" logotype featuring simulated rhinestone textures (must retain 3D relief appearance, not look flat). 2. The central angel/cherub graphic print (must undergo warping consistent with fabric folds). 3. The central metal zipper hardware. 4. Split kangaroo pockets. 5. Drop-shoulder seams which differentiate the silhouette from the user's current raglan-sleeve t-shirt. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the material transition (thin tee to thick hoodie), the target silhouette must expand outward by approximately 1.5 - 2.0 cm to account for fabric volume. The user's right hand (viewer's left) is in his pocket; the hoodie's hemline on this side must bunch upward and fold around the wrist, rather than hanging straight. The left arm (viewer's right) is relaxed; the sleeve should stack slightly at the wrist due to the cuff tension. - **Occlusion Handling:** 1. **Crossbody Strap:** This is the critical occlusion layer. The brown strap MUST be segmented and layered *on top* of the new hoodie. The physics engine must show compression/displacement where the strap digs into the thicker hoodie fabric across the chest and shoulder. 2. **Hand in Pocket:** The user's right hand and wrist must occlude the lower hem of the hoodie. 3. **Beanie/Head:** The hood of the source garment should remain down (on the back), ensuring it does not conflict with the existing beanie. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user image utilizes soft, diffused studio lighting (likely a softbox setup) coming from the front-left, creating soft shadows behind the user. The source image has harsh neon blue/purple contamination. The source texture must be neutralized (albedo extraction) to remove the blue tint and re-lit to match the user's neutral white balance. - **Color Calibration:** The hoodie is a light beige/cream. Once the neon cast is removed, the brightness must be calibrated so it doesn't look "blown out" against the white background, ensuring the shadow pass from the bag strap is visible on the light fabric. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute freeze on the user's face, skin tone, jawline, facial hair, and the accessories on the head (sunglasses and brown beanie). The neck area needs precise masking to transition from the t-shirt crew neck to the hoodie's split neck/hood structure. - **Body Integrity:** Do not alter the user's shoulder width or leg proportions. While the upper body volume will increase due to the "clothing layer," the underlying skeletal structure and the shape of the legs (jeans) must remain untouched. Do not perform any body slimming.
