PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a standard cotton jersey knit. It possesses a matte finish with low specularity (no shine). Unlike the user's current textured/crepe garment, the target t-shirt has a heavier drape with moderate stiffness. It should exhibit soft folds rather than sharp creases. - **Key Features:** The text "MORE THAN A SUPER HERO" is the focal point and must maintain legibility while wrapping around the chest curvature. The diagonal white tie-dye bleach effect must be preserved continuously across seams. The neckline is a crew neck (higher than current V-neck), and the sleeves are standard short sleeves. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The t-shirt is a relaxed fit. It should hang somewhat straight from the bust line down to the hips, avoiding the "cinched" look of the current garment. Tension folds should appear radiating from the armpits due to the user's arms being relaxed at her sides. The hemline will likely fall just above or slightly touching the clasped hands area. - **Occlusion Handling:** - **Hair:** The user has long dark hair draped significantly over her right shoulder (viewer's left) and partially over the left shoulder. This hair MUST be segmented and layered *over* the new t-shirt graphic. - **Hands:** The user's hands are clasped at the lower torso. The t-shirt hem must properly interact here—either falling behind the hands or bunching slightly if the shirt is long. - **Arms:** Since the source is short-sleeved and the user is currently wearing long bell sleeves, the system must generatively reconstruct/inpaint the user's bare forearms and elbows while maintaining accurate skin tone and lighting. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is in a room with warm, diffuse overhead lighting, casting soft shadows downwards and slightly to the right. The t-shirt requires ambient occlusion rendering specifically under the hair masses, the bust line, and inside the sleeve openings. - **Color Calibration:** The source image is lit with cool/neutral studio light. The t-shirt's green tones must be color-graded with a warmer temperature to match the yellow-ish ambient light of the user's room, preventing the "cut-and-paste" sticker look. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's face, jawline, and neck area above the t-shirt collar must be completely frozen. The specific facial expression and gaze must not be altered. - **Body Integrity:** Strictly forbidden to alter the user's BMI or shoulder width. The reconstruction of the arms (going from long sleeves to short sleeves) must reflect the user's actual wrist proportions and not default to a "model-thin" arm generation.
