I have a slight variation on the bridal party dance question.
Backstory: I am having two BM, both married to fantastic men who are also our friends. FI is having two GM, both of whom are very single. BM and GM do not know each other, in fact they have not yet met. First FI wanted to do a bridal party dance in which the BM and GM dance together with us. I have talked him out of this.
Now the question comes to announcements - do the BM and GM get announced together? OR should the BM be announced with their husbands and GM announced solo?
