Activity for Jordan

We are looking to have that invitation (bottom right) with a response card tied with a ribbon and wax seal. We're thinking of getting blue ribbon. But which color looks better? The copper (left) or the gold (right)? Hope you guys can give some...

The mother of the groom is looking at both dresses and can't really decide which looks better. Also another question, would this dress be a lil too heavy for a morning/early afternoon wedding? Hope you guys can help
