Ethereal ball gown portrait in a sunlit gothic library

A cinematic, highly detailed fantasy photograph of a beautiful blonde woman with her hair styled in an elegant updo, standing gracefully inside a majestic, sunlit gothic library. She is wearing a breathtaking, flowing emerald green ball gown made of tulle and tulle-like fabric, adorned with subtle gold glitter details that catch the light. The dress features an off-the-shoulder sweetheart neckline, layered with an optional intricate mesh, fishnet-style high-neck collar that covers her chest and neck. Golden bracelets adorn her wrists, and a delicate necklace rests on her collarbone. She stands in profile, looking off to the side with a soft, serene expression. A swirling cloud of magical golden dust and ethereal smoke surrounds her, illuminated by strong, warm sunbeams streaming through massive arched cathedral windows in the background. To her left, towering floor-to-ceiling wooden bookshelves filled with ancient books create a moody, academic, and enchanted atmosphere. The overall scene is filled with a dreamy, golden hour glow and deep volumetric lighting.
