We had a small wedding at a grange hall. (we did not elope)
I did not wear a white dress, instead I wore a long red print skirt and a white blouse. My husband wore a jacket with a tie in his breast pocket.
I did not get a diamond ring, honestly I dislike diamonds and we were so poor anyway.
It's your wedding. Do it exactly the way that it would be comfortable for you. If you decide you do want a party, don't let anyone's offers "oh, i'll sing for your wedding" overwhelm your sense of what YOU want.

I hated chanting the lovely vows out loud that we found in a book.
My husband, even though he is a lot more outgoing, blew his lines too.
Neither of my parents came to my wedding, they both had excuses.

I wore blue hiking boots under my floor length skirt and when we'd said "I DO" we both jumped off the stage. It was fun, and I have good memories of my wedding.
Good luck. Do it your way.
