I have to married couples in my wedding. 2 of my bridesmaids are married to 2 of my hubby's groomsmen. My question is do they have to be paired together? Is it ok for them to be lined up differently and walk with someone else? Is it ok that when they get introduced at the reception that they are introduced with who they walked with? I am printing my programs and do I have to list them together on there as well? What is the proper way for this?
