Vertical photorealistic portrait of a young woman wearing a white lace balconette bra, standing against a pale gray marble wall with subtle veining. She has long, wavy light brown hair with subtle balayage and natural makeup. Soft, diffused lighting creates warm skin tones, gentle highlights on the lace, and delicate shadows. Shallow depth of field keeps the subject in sharp focus while the marble background is softly blurred. Pose: shoulders relaxed, chest slightly forward, arms resting at her sides, conveying calm confidence. Color palette: white/ivory lace, creamy skin tones, warm beige, cool gray marble. Textures: intricate lace, satin-like strap details, smooth skin, cool marble. Style: high-resolution, cinematic realism, studio lighting.
