Not sure on what the standard is since my future in-laws will be paying for the rehearsal dinner. Do I invite my brothers and their spouses to the rehearsal dinner if they are not in the wedding? FH's sister and brother are both in wedding and so is my sister. My 2 brothers would be the only immediate family or siblings that would not be included and of course I would like them there. I can't imagine my in-laws saying no but I didn't know if it would be the standard for all immediate family to be there or if it would be rude to ask.
