PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment appears to be a medium-weight brushed cotton, flannel, or wool blend with a matte finish. It has high structural integrity (stiffness) around the collar and cuffs but allows for soft, gathered draping at the waist due to the pleats. It should scatter light rather than reflect it; no specular highlights (shine) should be applied. - **Key Features:** The specific "windowpane" check pattern (white vertical lines, dark reddish horizontal lines) must remain aligned across seams. The 5 visible white buttons, the sharp point collar, the dropped shoulder seams, and the unique waist pleating (which creates a gathered, blouson effect) are critical design elements. The balloon/lantern sleeve shape with fitted cuffs must be preserved. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The garment features dropped shoulders which must hang below the user's natural shoulder point. The sleeves are voluminous (balloon style) and should not cling to the user's arms like the current black top; they must puff out before gathering at the wrist. The hemline is cropped/waist-length; it should sit near the user's natural waist, flaring slightly due to the pleats, rather than hugging the hips. - **Occlusion Handling:** The loose strands of hair framing the user's face and neck must be segmented and layered *over* the new collar and shoulder area. The gold necklace should be preserved if the collar is simulated as open; otherwise, it is occluded. The user's red/orange bracelets on the wrists must either be layered *over* the cuffs or covered, depending on final sleeve length calculation (likely just touching the bracelets). PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user environment features strong backlighting (blooming light from the curtains) and soft, diffuse frontal fill. The new garment must exhibit "rim lighting" or a slight halo effect on the shoulder edges to match the background intensity. Shadows should be soft and generally fall towards the center of the torso, mimicking the diffuse ambient room light. - **Color Calibration:** The user image has a warm, yellow-tinted color temperature due to the floral curtains. The source garment (cool green) must be color-graded with a slight warm overlay to integrate naturally into the scene. The contrast of the black lines in the plaid pattern should be slightly lowered to match the somewhat hazy/soft focus of the selfie. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's eyes, nose, lips, jawline, and ear structure must be completely frozen. The specific hairline and loose hair strands are strictly protected. - **Body Integrity:** The user's shoulder width and torso length must dictate the scaling of the cloth. Do not slim the waist or alter the user's pose. The colorful skirt visible at the bottom of the frame must remain untouched and distinct from the new shirt's hemline.
