PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is constructed from corduroy (likely cotton blend). It possesses a rigid structural integrity with a velvety, ribbed texture. Unlike flowy fabrics, this material resists folding and will create "hard" geometric creases rather than soft drapes. Light should interact with the vertical ridges, creating alternating micro-shadows and matte highlights. - **Key Features:** The Minnie Mouse all-over print must maintain aspect ratio and not warp excessively across the bust. Critical geometry includes the puffed/gathered shoulder seams, the structured shirt collar, the snap-button placket (currently buttoned), and the two large patch pockets on the chest. The "H&M" tag inside the neck should be removed during transfer. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The target user is standing with a slight hip tilt. The garment is a structured jacket/overshirt and should sit somewhat "boxy" on the user's frame rather than clinging to the skin. The shoulder puff sleeves need to maintain their volume and not flatten against the user's deltoids. The sleeves are long and gathered at the cuff; they must extend to the user's wrists, covering the current bare arms. - **Occlusion Handling:** 1. **Hands & Phone:** The user's hands are clasped at the waistline, holding a phone. This is a critical high-friction zone. The new garment's hemline and lower sleeve cuffs must be masked *behind* the hands and phone. 2. **Hair:** The user's dark, shoulder-length hair rests on her shoulders and upper chest. Precise segmentation is required to layer the hair strands *over* the new corduroy collar and shoulder panels. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The User Image features diffuse, cool-toned indoor event lighting (likely fluorescent or LED), casting soft shadows downward. The source garment (warm beige/cream) must be desaturated slightly and tinted with a cool cast to match the ambient light reflected from the large purple backdrop. - **Color Calibration:** The stark white brightness of the source image studio lighting must be lowered to match the exposure of the user's grey trousers. Shadows cast by the collar onto the neck and by the cuffs onto the wrists must be generated to ground the garment in the scene. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute freeze on the user's face, specifically maintaining the position and reflection of the eyeglasses, the jawline definition, and skin tone. - **Body Integrity:** STRICT PROHIBITION on warping the user's body mesh. The simulation must fit the garment to the user's existing measurements (bust, waist, hips), preserving her natural silhouette. Do not slim the torso or alter the width of the shoulders.
