The Q: I am having a small destination wedding, but want to have a big formal reception when I return to New York. Should I still wear my wedding dress, and how could the wording on the invitation go?
The A: First, YES, you can TOTALLY wear your wedding dress again. In fact, it will give everyone a chance to see how great you looked. Obviously, if it's very beachy and your post-wedding reception is very formal, it may not be totally appropriate, but assuming it's in line with your other affair, it should be great and you should not feel weird at all!
For the wording try something like (if you are hosting yourself):
Deborah and Steven Nolan
request the honor of your presence
at a celebration of their marriage
Saturday, the Twenty-second of August
at seven o' clock in the evening
