I realize that this decision is ultimately up to my fiance and I and there may be no proper etiquette for this, but interested in your opinions. I want to ask my brother to walk me down the aisle and have a brother/sister dance instead of father/daughter, since my father passed away a few years ago. We have a close relationship and I feel that would be a pretty big role in the wedding, would it be too much if he was also a groomsman?
