My DH has been asked by his sister to walk her down the aisle, one week before the wedding!! We were just going to be guests but now he needs to change his suit color and shirt. She is having a small (50 people) at the Carnton Plantation. She says her wedding colors are tan and brown. he has a blue suit and a black one. Any ideas on which suit to wear and which shirt and tie color. He needs to purchase them on Monday as he is driving his mother (she lives in Columbus OH) to the wedding (he lives in Detroit) and needs to leave early on Tuesday.
