Three sons here, and when they all had traditional church weddings, ( plus daughter did too) all the guys wore a tux. That thing about renting so many at once may offer one free, make sure you tell your son about that, and that your hubby needs the free one! There has been a lot of money spent on tux rentals in our family, our boys had lots of good friends. LOL I understand the cost factor, but it does mamke a difference in the photos . Daughters wedding ,everyone wore long dresses and pastels, except the grooms mom. She wore a short red dress, and it rerally spoiled the looks of the group photos. Big deal??? Probably not in the long run, but it did seem to matter then. Talk to son!!!!!
