A highly detailed photorealistic portrait of a glamorous young woman in a vintage 1950s Hollywood pin-up style, with voluminous blonde hair styled in soft victory rolls and tousled bangs framing her heart-shaped face, fair porcelain skin, large expressive blue-green eyes, subtle rosy cheeks, full lips in a soft neutral expression, and dangling pearl earrings. She wears an elegant off-the-shoulder white satin ball gown with puffed gigot sleeves, intricate pearl bead embroidery along the deep plunging V-neckline accentuating her décolletage, fitted bodice, and flowing skirt. Her hands are elegantly posed in pristine white silk elbow-length gloves, one hand delicately holding slender green gladiolus stems, the other near a lush bouquet of vibrant pink roses. Composition is a close-up three-quarter view against a deep burgundy-black velvet theater curtain backdrop, with a tall ornate stand of dozens of blooming pink roses towering on the right side, and a classic vintage studio spotlight on a tall black metal stand casting warm golden highlights and soft dramatic shadows from the left, creating high contrast chiaroscuro lighting with a subtle vignette. Ultra-high resolution, sharp focus on face and details, cinematic depth of field, rich color palette of creamy whites, lush hot pinks, deep blacks, and golden highlights, in the style of professional fashion photography by Richard Avedon or Norman Parkinson, 8k, hyperrealistic textures on fabrics, flowers, and skin.
