Best Man: Can I Have More Than One Best Man?
I want to have two girlfriends stand up with me at my wedding -- a maid of honor, as well as a matron of honor. Since I like symmetry, there needs to be two men on the groom's side, but what would their titles be? We don't want to designate one as more important than the other.
In the same way that you'll have two honor attendants, just make both of them best men. Everyone's honored and happy!
