Ultra-realistic high-fashion studio portrait of a woman [image uploaded], vertical composition, framed from mid-chest to top of head. Camera at eye level, straight-on angle with a very slight head tilt to the subject’s left. Posture & pose: upright posture, shoulders relaxed. Left shoulder slightly forward, creating a gentle diagonal line across the collarbones. Arms relaxed out of frame, fur wrap resting naturally over the shoulders. Expression: calm, elegant, and composed. Soft neutral gaze directly into the camera, slightly parted lips with a subtle natural gloss. No smile, refined and confident mood. Face & skin: smooth fair skin with realistic texture and pores, soft luminous finish (not plastic or airbrushed). Rosy blush concentrated on the apples of the cheeks. Natural highlight on nose bridge, cheekbones, and collarbones. Eyes & makeup: large almond-shaped eyes, cool gray-brown irises. Long curled lashes, soft eyeliner, muted rose eyeshadow blended outward. Straight natural brows with gentle arch. Hair: short black bob cut just above the shoulders, slightly wavy ends. Center part with soft wispy strands framing the face. Large black satin bow tied at the back of the head, visible above the crown. Accessories: silver floral drop earrings with dangling details. Matching silver statement necklace with a central floral pendant resting at the upper chest. Clothing & styling: beige satin slip dress with thin spaghetti straps, smooth fabric with subtle sheen. Black faux-fur stole draped loosely around both shoulders, adding contrast and texture. Background: clean seamless light gray to off-white studio backdrop, evenly lit with no visible texture or distractions. Lighting: soft diffused beauty lighting from the front and slightly above eye level. Gentle fill light to reduce shadows, subtle rim light outlining hair and shoulders. Balanced highlights without overexposure. Color palette: neutral beige, black, silver, soft pink skin tones, minimal and elegant. Camera & settings: full-frame DSLR or mirrorless, 85mm lens, f/2–f/2.8, ISO 100, high sharpness on eyes, shallow depth of field. Image quality: ultra-high resolution, professional fashion photography, crisp details, natural skin realism. Strictly photorealistic human portrait — no illustration, no anime, no CGI, no digital painting, no doll-like skin. 一隻在香港茶餐廳喝奶茶的貓 Use the original face exactly as it is, without changing a details. A hyper-realistic, highly detailed portrait of a beautiful woman in a 1950s/Pin-Up style, evoking the essence of a classic Hollywood starlet on a glamorous vacation.
• Subject: A stunning young woman with a classic Pin-Up aesthetic (think 1950s movie star).
• Facial Features: Striking blue/green eyes, perfectly arched eyebrows, and classic makeup featuring bright red lipstick. Her expression is captivating and seductive.
• Hair & Hat: Long, voluminous, deep brown hair styled in soft, glamorous waves/curls. She is wearing a very large, wide-brimmed straw hat that casts a soft shadow on her face.
• Attire: A chic, form-fitting black dress with white polka dots. The dress has an off-the-shoulder, sweetheart neckline bodice that cinches at the waist with a thin black belt. She is also wearing a black scarf with white polka dots tied around her neck like an ascot.
• Setting & Context: The background suggests a sunny, coastal location with a deep blue ocean/sea visible behind her. She is leaning seductively against the tan/brown, polished hood or door of a classic vintage convertible car.
• Style/Vibe: Vintage glamour, 1950s Hollywood, high-fashion editorial.
