Ensure the replacement garment appears natural, properly tailored, and complements the subject's overall presentation (such as professional shirt, refined blouse, contemporary blazer, or sophisticated layered separates).  Pose & Gaze: Position shoulders square to the camera, maintaining perfect frontal alignment. Direct the gaze straight ahead into the lens at identical eye height, avoiding any angular deviation in vertical or horizontal planes.  Expression: Display a professional neutral demeanor or subtle closed-lip smile that conveys confidence and authenticity.  Background: Utilize a solid, consistent light gray photographic background (color code: #d9d9d9) without any pattern, texture, or tonal variation.  Lighting & Quality: Apply balanced studio-quality illumination eliminating harsh contrast or reflective artifacts. Deliver maximum resolution imagery with precise focus and accurate natural skin color reproduction."
