PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment appears to be a medium-weight woven cotton or cotton-blend with an Ikat weave. It possesses a matte finish with low specular reflection. The fabric has structural stiffness to support the gathered tiers (peplum) at the waist but allows for movement. It creates soft, voluminous folds rather than sharp creases. - **Key Features:** The distinct "Ikat" pattern (vertical white blur on pink base) must be preserved without distortion. The dual-tiered ruffled hemline (peplum style) is critical. The wide/square neckline and short cap/puff sleeves are essential design elements that differ significantly from the user's current crew-neck long-sleeve top. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** This requires a sleeve-length modification (Long-sleeve Source -> Short-sleeve Target). The simulation must generate accurate skin texture for the user's arms where the black sleeves currently exist. The bodice should fit snugly across the chest, but the waistline must release into the tiered flare, sitting *over* the user's denim waistband rather than tucked in. The fabric should drape vertically from the bust point, bunching slightly where the tiers gather. - **Occlusion Handling:** 1. **Phone & Hands:** The user's right hand and the smartphone are the primary occlusions. The pink garment must be rendered logically *behind* the phone and fingers. 2. **Hair:** The user's dark hair falls over both shoulders. The new neckline and shoulder seams must pass *underneath* the hair strands. 3. **Handbag:** The handbag held in the left hand is below the hemline, but the strap/chain needs to be checked; if it hangs near the hip, the garment ruffles must not clip through it. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user environment features high-intensity, multi-source overhead artificial retail lighting (cool white LEDs). This differs from the source's natural/warm ambient light. The transferred garment must be re-lit to cast soft, diffuse shadows downward (self-shadowing under the ruffles). The "warmth" of the pink fabric must be cooled slightly to match the store's color temperature. - **Color Calibration:** The white Ikat pattern on the shirt must be color-graded to match the white balance of the store's ceiling lights/reflections to ensure integration. The saturation of the pink should be preserved but balanced against the lower contrast of the retail environment. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's visible facial features (forehead, eyes, nose, mouth), skin tone on the face/neck, and existing hairstyle are absolute freeze zones. - **Body Integrity:** Strictly forbidden to alter the user's BMI or silhouette to match the source model. The garment must expand to fit the user's natural measurements. Crucially, the skin generation for the new exposed arms must flawlessly match the user's facial skin tone, respecting her specific complexion without smoothing or lightening.
