PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a bomber jacket, likely made of a polyester or satin-blend synthetic. It possesses a semi-matte finish with low-to-medium specular highlights (unlike the high absorbency of the user's current knit top). The ribbing at the collar, cuffs, and hem is stiffer and elastic, while the body fabric is lightweight but holds structural volume, creating soft, rounded folds rather than sharp creases. - **Key Features:** The high-contrast botanical/fern print must remain sharp. The solid black ribbed collar, cuffs, and waist hem are critical boundary markers. The silver central zipper acts as the vertical centerline. The "pouching" effect typical of bomber jackets above the waistline hem must be preserved to maintain the garment's specific style. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the user's semi-profile pose (approx. 45 degrees), the jacket must wrap around the torso, obscuring the far right side. Since the source is long-sleeved and the user is wearing short sleeves, the simulation must generate realistic fabric draping over the exposed forearm. The fabric should bunch horizontally at the inner left elbow (cubital fossa) due to the slight bend in the user's arm. The back of the jacket should hang slightly away from the lower spine, reflecting the loose fit of a bomber cut. - **Occlusion Handling:** The user's long dark hair falls over the left shoulder and upper chest. This is a critical occlusion layer; the jacket collar and shoulder panel must be rendered *behind* these hair strands. The user's left hand and wrist watch (if present) must remain visible, meaning the jacket cuff must terminate precisely at the wrist bone, layered *under* the hand but *over* the forearm. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is illuminated by a soft, diffuse light source from the front-left, casting a soft shadow on the wall to the right. The rendered jacket must accept highlights on the left shoulder and left outer sleeve. Shadows must be cast within the fabric folds at the elbow and under the collar. The black values of the jacket must match the black point of the user's current trousers and hair. - **Color Calibration:** The user image has a warm, slightly grainy indoor tint. The source jacket is currently cool/neutral studio white. A warm filter (slight sepia tone curve) must be applied to the jacket's white floral patterns to integrate it into the room's ambient temperature, preventing it from looking like a pasted "sticker." PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's entire head, facial expression (smile), neck area above the clavicle, and hair structure are to be frozen and masked out of the generation area. - **Body Integrity:** Strict prohibition on body warping. The user's shoulder width, arm thickness, and torso volume must be maintained. The bomber jacket adds natural volume; do not slim the waist or flatten the chest to compensate for the garment's bulk. The silhouette should expand slightly to accommodate the jacket's padding, not shrink the user.
