So is it "mandatory" to put your fiance's sister(s) in your wedding? I'm just wondering, because I have no intention of including them in my bridal party (when we do get hitched). Not because of anything personal, but simply because we aren't "friends". Our only connection is him. They haven't shared life experiences with me like my friends have. If anything I will like for them to serve as a hostess or something. Am I wrong and just looking for conflict?
