I just read all 6 pages of this thread. OP, that invitation is beyond tacky! In so many ways!
OK, my recommendation, FWIW, is to send your polite regrets, even if this is your future SIL. My reason for saying this is that any compromise -- like going and not wearing a cocktail dress, leaving early, not staying overnight -- is potentially much more awkward than just declining outright.
Remember, you never, ever, have to give an explanation for declining an invitation, and it is beyond rude for the inviter (or honoree) to require one. If anyone asks, just smile sweetly and say that you are sorry but you have a conflict on that date.
I'd also not discuss the invitation further with anyone who knows you all, some people just thrive on gossip. I'd not even tell your Mom why you won't be going. Future SIL may ask her and you don't want to put your Mom on the spot!
Part of me really wants you to go though, so you can report back here!
