A woman with dark hair stands in the center aisle of a cathedral, facing forward, wearing an intricate, heavily embellished gold and silver mermaid gown that is a faithful recreation of the specific design provided in your reference images, including the gold cape draped from her shoulders and trailing on the floor. In the background at the altar, a couple, identified as Clara in a white wedding gown and Kim Juhoon in a black tuxedo, stand looking forward. The church is filled with seated guests in pews, many of whom are looking toward the woman in the aisle with expressions of shock and surprise, hands covering their mouths, in a state of speechlessness. Natural light streams in from a window on the right and illuminates the altar, while the cathedral's Gothic architecture, including stone archways and pews, fills the scene. Musicians are visible near the altar, adding detail to the formal, elegant environment.
