My fiance's parents are divorced and both remarried. He keeps going back and forth on both his dad and stepdad wearing tuxes (or just his dad) on the wedding day. His mom really wants his stepdad in one. My fiance doesn't want to hurt anyone's feelings. He doesn't want his dad to get mad that his stepdad is in a tux. Including dad/stepdad, mom, grandparents, etc. Opinions/Suggestions, please!
