All of my and my fiance's extended family and friends are in Oregon where we currently live. We want to have a "reception" like one would have at a traditional wedding before we move across country to Kentucky. However we won't be officially married until a few months later where we are having a small ceremony with just our parents and witnesses. We've decided to have the ceremony there because our parents can't fly out and it is very important for them to be there. But we don't want to forget the majority of our friends and family still in Oregon.
Is there anything wrong or presumptuous with having a reception "wedding" party if we aren't officially married yet?
