Black and white by the high window

Photorealistic vertical 3:4 indoor portrait. An adult woman sits sideways on a window-side bed looking at the city at left. Black one-piece swimsuit under a white sheer long-sleeve cover-up. Two-thirds profile to the left, lips slightly open. Slightly long oval, slim chin, wide eyes and long lashes, thin straight brows, slim nose, small tip, glossy pale coral lips. Near-center part, long sheer bangs, dark-brown long waves to below the chest. Black one-piece with thin straps, deep V, small edge frills, black bow at center bust, side gathers and long adjustment ties at the waist. White chiffon open-front cover-up with two-tier flared cuffs. Legs folded sideways, left hand on the bedding, right hand on the right thigh. Black-framed large window and blurred high-rise city and mountains at left, thin white curtain at right, pale-gray bedding and cushions below. Soft diffuse light from the right curtain side, strong contrast with the black swimsuit. Camera at bed height, thighs-up. Subject occupies center to right, folded legs cropped at bottom, city as left negative space. Face and outfit sharp, city shallow-soft. Clean low-saturation. Adult woman only. Do not omit the side gathers and ties; do not make the white sheer sleeves opaque. No text, no watermark.
