I an unsure what to do with my wedding party... My fiancee and I are thinking of just asking our siblings to be the "attendants of honor." If my fiancee's brother is the best man and my brother is the attendant of honor, what special title could we use for his sister? In this case, I would not have a maid of honor.
If we include my best friend in the mix, and call her the maid of honor, does this take away from my brother being my honor attendant, or would all 4 people be of equal status at that point??
If you are just having the two attendants (his sister and your brother) they could share the duties of honor attendant. It probably wouldn't work well if your friend was the maid of honor, your brother as honor attendant, and your future sister in law as a bridesmaid. She may feel as if she is the third wheel. What may work well is for your brother to be your honor attendant, with the sister and friend as bridesmaids. This way your brother still has the honored position and the other two are on the same special level together.
