My father, my brother (who is a bridesman), my fiance, and the groomsmen are all going to be wearing tuxes for the wedding. My future FIL does not want to wear a tux or a suit. He doesn't even like to wear dress pants. My fiance said he has to discuss with his father what he is willing to wear. What does the father of the groom normally wear? My personal opinion is that he will look weird in family photos being the only guy not wearing a tux, but I know we can't force him to wear a tux.
