The guys are wearing black suits in the wedding instead of tuxs. My step-dad, who is giving me away, already has a suit that is dark grey with a pinstriping that my mother says you can't see until you get real close. He is also planning on wearing dress shoes while the groom wants his groomsmen in black square-toe western boots. My parents don't really have the money to go buy a new suit for my step dad that is black, matching the rest of the guys or boots. Will this look bad?
