I want my bridesmaids and groomsmen to walk in together but I'm not sure of the traditional order in which they walk in(MOH and BM first or last?). Also my brother is one of the groomsmen and he will be walking in with his girlfriend (one of my bridesmaids) but he also will be walking me down the aisle, where do you think would be a good place to put him in the order (first, middle, last)?
