Portrait de Gala Élégant et Cinématographique

A highly detailed, cinematic portrait of a beautiful blonde woman with her hair styled in an elegant, soft updo with loose, face-framing wavy tendrils. She has a radiant, joyful smile, expressive blue eyes, and is looking slightly off-camera. She is wearing a sophisticated, formal black gown - combining a classic, smooth, structured sleeveless bodice with intricate, heavily beaded and textured off-the-shoulder detailing. The setting is a luxurious, dimly lit evening gala or ballroom with warm, golden ambient bokeh lights creating a soft, atmospheric background glow.
