PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a cotton-jersey blend or rib-knit material, likely with elastane content. It features a matte finish with high elasticity (stretch). Light reflection should be diffuse and soft (lambertian), avoiding specular highlights typical of synthetics or silks. The tension map should show slight stretching across the chest area rather than loose draping. - **Key Features:** The central graphic text "LOS ANGELES 1989 California" in pink outline is the critical focal point and must remain legible without excessive warping. The pink overlock stitching (exposed seams) running vertically down the bodice (princess seams) must be preserved to define the garment's structure. The neckline is a scoop neck, distinct from the user's current V-neck. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Since the source garment is a fitted tank/bodysuit, it must conform closely to the User's torso, replacing the loose, tulip-hemmed volume of the original black top. The garment should follow the curvature of the bust and waist, terminating at the waistband of the user's existing beige trousers to simulate a tucked-in or bodysuit fit. - **Occlusion Handling:** 1. **Hair:** The user's dark hair falls over both shoulders and rests on the clavicle area. The white tank straps must pass *underneath* these hair segments using precise alpha masking. 2. **Necklace:** The large bronze/gold coin necklace sits on the upper chest. The new scoop neckline will likely intersect with this area. The necklace must be segmented and layered *over* the white fabric where overlap occurs. 3. **Arms/Cuff:** The gold cuff on the right wrist is safe, but the inner arms must be cleanly separated from the new white texture to avoid texture bleeding. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The User Image features soft, directional studio lighting coming from the front-left, casting a shadow on the wall to the right. The white garment must generate self-shadowing on the user's right side (viewer's right) and under the bust to match this ambient occlusion. - **Color Calibration:** The Source Image has a cool, bluish background temperature. The User Image is warmer with beige tones. The white value of the new top must be white-balanced (warmed slightly) to match the User's room tone, preventing the white fabric from looking blue or fluorescent against the user's skin. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute pixel preservation required for the user's face, specifically the eyes, nose, lips, jawline, and the hairline/forehead area. - **Body Integrity:** The user's shoulder width, arm circumference, and waistline geometry must remain unaltered. The "slimming" effect often seen in source models must not be applied to the Target User; the garment must stretch to fit her actual anatomy, not warp her anatomy to the garment.
