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.
