My BM's are some of my closest friends since elementary and middle school. I have one SIL, she and my brother married 10 years ago and have been together for 15. Their daughter will be a Jr. BM. I would love to have her (SIL) involved in one way or another. My aunt suggested she could be a bridal attendant. What does this role involve? are any of you having one in your wedding party? Other suggestions are welcomed.
