PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a cotton jersey blend (standard athletic t-shirt). It has a matte finish with low specular reflection. It possesses medium drape weight—meaning it will conform to the body but maintain some structural rigidity, unlike the current lightweight, flowy patterned top. It should exhibit soft, rolling folds rather than sharp creases. - **Key Features:** - The "adidas" Trefoil logo and text on the left chest must warp accurately across the breast curvature. - The three white stripes running down the shoulders/sleeves are structural anchors and must align with the user's deltoids. - Contrast white ribbed crew neck and arm cuffs. - The small white tag on the bottom left hemline. - The deep maroon/burgundy color consistency. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** - **Shoulders/Sleeves:** Unlike the current sleeveless top, the t-shirt sleeves will cover the upper deltoids. The right sleeve (viewer's left) must bunch slightly at the top due to the raised arm pose. The left sleeve (viewer's right) will hang naturally but stretch slightly across the bicep due to the hand-on-hip pose. - **Torso:** The t-shirt has a straighter cut than the current fitted, peplum-waist top. It should hang more vertically from the bust down, obscuring the current waist indentation and eliminating the peplum flare at the hips. - **Neckline:** The crew neck is higher than the current V-neck. It will sit closer to the clavicles. - **Occlusion Handling:** - **Hair:** The long strands of hair falling over the user's right shoulder (viewer's left) and right arm MUST be segmented and layered *over* the new t-shirt fabric. - **Right Hand:** The fingers touching the neck/clavicle area are critical. The new crew neckline will likely sit very close to or underneath these fingers. The fingers must occlude the fabric, not be covered by it. - **Left Arm:** The silver bangle and the tattoo on the left arm (viewer's right) must remain visible. If the t-shirt sleeve is long enough to cover the tattoo, the tattoo should be hidden; if the sleeve ends above it, the tattoo must be preserved. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user image features high-key, diffuse studio lighting with a primary source from the upper-front-left. The t-shirt must be rendered with soft ambient occlusion. Shadows should fall on the right side of the torso (viewer's right) and under the bust. - **Color Calibration:** The source image has a slightly yellow/warm cast. The rendered t-shirt needs to be color-corrected to a true deep maroon to match the neutral white balance of the user's studio setting. The white stripes must be bright white, not cream/yellowed. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The entire head area, including the jawline, neck structure above the clavicle, and the dangling silver earring on the left ear, must be frozen and untouched. - **Body Integrity:** Do not slim the user's waist to match the current fitted top. The simulation must respect the user's actual biological volume. The arms, specifically the skin texture, tattoo, and bangle, must remain unaltered outside the masked clothing area.
