ushers

Hi ladies,
My FH and I are trying to work out our bridal parties. I will be having 8 bridesmaids and 1 maid of honor. (One bridesmaid is his sister and 2 are his sister in laws) He can't figure out what to do. He has 3 brothers that he wants involved, as well as my 2 brothers in law. He's thinking of makimh his 3 brothers his best men and my brothers in law his ushers. Any thoughts on this???

Thanks!
