Preferably by July 10th. However, the earlier the better!
The ceremony will start at 2pm, so give yourself enough time to make it to the church and be seated before the ceremony begins.
If you feel as though you should bring a guest (1), make sure to note this when you RSVP. If you don't note that you are bringing a guest, we'll assume it's just you. We need to have an accurate head count!
Yes, please wear clothes. ;)
