PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a structured silk or satin blend with metallic thread embroidery. Unlike the user's current soft flannel, this fabric has high stiffness (due to likely boning or interfacing in the bodice) and low elasticity. It exhibits anisotropic reflection—the metallic gold stripes will have sharp specular highlights, while the maroon base will have a soft, sheen-like luster. - **Key Features:** The sweetheart neckline, thin spaghetti straps, and the specific chevron (zigzag) gold pattern alignment must be preserved. The cropped hemline is critical; it must terminate above the natural waist. The structure of the bust cups needs to be maintained even in the profile view. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The user is in a profile/rear-oblique stance. The simulation must extrapolate the side and partial back view of the garment based on the frontal source image. The garment must sit tight against the torso (skin-tight fit) rather than hanging loose like the current flannel. The simulation must generate realistic skin texture for the user's currently covered arms, shoulders, and lower back, as the source garment is significantly more revealing than the target garment. The hem must follow the curvature of the user's ribcage. - **Occlusion Handling:** The user's hair, styled in a messy updo with a claw clip, falls slightly over the nape of the neck. The new garment's shoulder straps and rear neckline must pass *underneath* any loose strands of hair. The user's left arm (visible in foreground) will partially obscure the side seam of the crop top. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The scene is illuminated by warm, overhead string lights (tungsten/orange hue) with a secondary cool, ambient night light from the background (blue/cyan). The new garment must reflect the warm overhead lights on the upper surfaces of the metallic gold stripes, while the lower sections of the bodice should fall into deep shadow to match the nighttime setting. - **Color Calibration:** The source image is high-key studio lighting. The garment's exposure must be significantly lowered. The maroon color must be color-graded to interact with the warm yellow cast of the environment, likely shifting slightly warmer in highlights and desaturated in shadows. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's ear, jawline, visible cheek profile, and glasses frames must be frozen. The specific texture and volume of the hair in the claw clip must remain untouched. - **Body Integrity:** The user's standing posture and arm thickness must not be altered. The generation of the exposed skin (arms/shoulders) must match the skin tone and texture visible on the user's face and hands, without slimming the torso or artificially smoothing the skin to "doll-like" perfection.
