Activity for Huston

This is what I have so far, and I can't decide on the following: -napkin ring color (napkins are the same ivory as the tablecloth) -charger color (was thinking red, with red napkin ring) - if ivory plates with gold rim work? -fairy lights in vase?...

I am IN LOVE with this dress, but it's an impossible amount above my budget. I want to look for similar styles within my budget, but don't know how to describe this in terms of Style or Silhouette. Any ideas?
