Sophisticated Evening Gown Color Change Silver

Design a sophisticated evening gown featuring:

1. Color: Change from silver to a rich emerald green.
2. Material: Use a soft satin instead of sequined fabric for a smooth finish.
3. Silhouette: Modify the cut to a classic A-line instead of a form-fitting style.
4. Neckline: Shift from a deep V to a subtle sweetheart neckline.
5. Details: Replace the fringe with elegant draping on one side for added flow.
6. Setting: Depict the model in a modern, upscale atrium filled with natural light and lush greenery.

Ensure the atmosphere reflects an elegant soirée vibe without any brand references.
