Noir et blanc portrait studio éditorial de mode

2:3 vertical, photo-realistic black and white fashion studio shoot. An adult white female, clearly aged 22-28, crouches on a low black wooden square platform, near full-body composition, captured from head to high heels. The subject is centered, in a tight low crouch: one leg bent horizontally across the front of the body, the other leg raised with knee bent and extended to the right, forming a clear triangular geometric structure; upper body slightly leaning forward, one hand naturally hanging between the legs, the other hand relaxed at the knee. She looks directly at the camera, expression calm, confident, slightly sharp, not smiling. She has a delicate oval face, clear jawline, light almond eyes, natural thick eyebrows, straight nose bridge, and full natural lips. Long, thick, light blonde hair in loose, messy large waves, naturally falling to chest and back, with visible volume at the roots and many fine flyaway strands. Makeup is minimal but high-fashion, emphasizing the eyes, brow shape, and facial bone structure, no excessive skin smoothing. She wears a white woven athletic jacket, baseball collar, front zipper, loose sleeves, with black double stripe trim on the collar, cuffs, and hem; two black vertical athletic stripes on the outer sides of both sleeves; the jacket front is wide open, creating a bold deep V visual line. Bottom is black high-waisted inner shorts or simple briefs, overlaid with black fine fishnet tights, the net texture extending from the hips to the ankles, with a wider black lace trim band at the top of the thighs. Feet in black pointed stiletto heels, sleek and simple. Background is a seamless dark gray to near-black studio backdrop, no props, only the low wooden platform underfoot. Key light from a large softbox at front left, creating sculptural side lighting, with bright gray highlights on the face, hair, white jacket, and legs, gradually falling into deep gray shadow on the right; subtle rim light separates hair from background. Fully black and white, deep blacks, rich mid-tones, soft highlights, low to medium contrast. 85mm or 50mm lens, f/2.8-4, ISO 200-400, full subject in focus, soft background falloff. Realistic skin pores, hair strands, fabric wrinkles, fishnet grid, and leather shoe reflections, subtle ISO 400 film grain, black-and-white fashion editorial, sport-luxe styling, cinematic studio portrait, photorealistic, natural anatomy, no plastic skin, no excessive retouching, no text, no logo, no watermark.
