Thinking Process
PHASE 1: VISUAL DECONSTRUCTION
- **Fabric Physics:** The source garment is a lightweight bomber jacket, likely composed of a viscose or polyester blend. It possesses a semi-matte finish with low specularity. Unlike the user's current cotton jersey top, this fabric has higher structural integrity but is not rigid. The ribbed collar, cuffs, and hem (black elasticated fabric) create tension points where the fabric will gather and bunch, rather than draping heavily like a knit.
- **Key Features:** The high-contrast black and white floral/botanical print must remain distinct without blurring during the warp. The central silver metal zipper (currently closed) acts as the vertical anchor. The solid black ribbed texture on the collar, wrist cuffs, and waist hem defines the silhouette boundary. The side pocket welts are subtle but must be preserved to maintain realism.
PHASE 2: FIT & DRAPE SIMULATION
- **Body Mapping:** Due to the user's seated posture, the jacket's waist hem will ride up slightly and fold near the hip crease/lap area. The sleeves must follow the bend of the elbows; specifically, the fabric on the inner elbow (antecubital fossa) must compress/fold, while the outer elbow fabric stretches tight. The shoulder line of the bomber is slightly dropped; this volume must be added on top of the user's natural shoulder line, replacing the tighter fit of the pink shirt.
- **Occlusion Handling:**
1. **Hair:** The user's dark, shoulder-length hair falls over both clavicles and the upper chest. This is a critical occlusion layer; the hair must be masked and composited *over* the new jacket collar and shoulders.
2. **Hands & Wrists:** The user's hands rest on their thighs. The jacket cuffs must stop at the wrists, sitting *behind* the hands.
3. **Accessories:** The bracelets/bangles on the left and right wrists must be preserved and rendered *over* or emerging from the jacket cuffs.
PHASE 3: ENVIRONMENT & LIGHTING
- **Light Match:** The user is in an indoor environment with cool, diffuse overhead fluorescent lighting (note the highlights on the forehead). The source jacket is flat-lit. We must introduce soft shadowing into the folds of the jacket (armpits, inner elbows) and cast a contact shadow where the jacket touches the yellow sofa. The lighting direction is top-down and slightly front-facing.
- **Color Calibration:** The "white" floral pattern on the jacket must not be pure #FFFFFF. It must be graded to match the room's white balance (slightly cool/cyan tint) and absorb a subtle amount of reflected yellow light from the sofa on the side panels to integrate the subject with the background.
PHASE 4: IDENTITY PROTECTION
- **Facial Lock:** The region from the neck up (chin, jawline, nose, eyes, forehead) is strictly frozen. The hair geometry is locked.
- **Body Integrity:** The simulation must respect the volumetric displacement of the user's seated torso. DO NOT slim the waist or arms. The bomber jacket adds layer volume; the final silhouette should be slightly bulkier than the original image, not slimmer. The legs and black jeans must remain unaltered.
