A stylish adult woman posing in a modern luxury bathroom, leaning casually against a marble countertop. She stands in a confident, elegant posture with one leg slightly bent forward, creating a natural S-curve. The setting is minimalist and upscale: grey marble walls, geometric stone floor tiles, warm ambient lighting reflected from under-counter lights. She wears a fitted one-shoulder mini dress in soft ivory tones, draped and ruched to emphasize the silhouette. The fabric looks smooth and slightly elastic, hugging the body without exaggeration. One sleeve is long, the other shoulder bare, adding a high-fashion asymmetry. She holds a small sparkling evening clutch in one hand, relaxed but intentional. Her expression is calm, self-assured, slightly sultry. Eyes focused just past the camera, lips neutral, face softly contoured. Makeup is polished and evening-appropriate: sculpted cheeks, defined brows, subtle glow on the skin, nude lips. Jewelry is minimal and refined, adding to the “quiet luxury” feel. Lighting is a mix of warm indoor ambient light and direct flash, creating sharp shadows on the walls and crisp highlights on skin and fabric. Textures of marble, fabric folds, and skin are clearly visible. No blur, high clarity, editorial fashion photography vibe.
