Surreal Bioluminescent Underwater Fashion Film

Create a 30 second surreal fashion film in 3:4 aspect ratio. A young woman with pale skin and floating dark hair, wearing a massive, bioluminescent glowing gold silk ballgown, walks barefoot on the edge of a jagged, pure black underwater trench. The environment is pitch black, illuminated only by her golden dress. The camera moves slowly, capturing the underwater physics of her dress and hair. She steps to the very edge of the abyss and leans backward over the void, suspended horizontally by a powerful underwater current. Perfect serenity on her face. Extreme contrast, OLED blacks, glowing gold highlights, cinematic slow motion, photorealistic underwater lighting, ultra-detailed.
