My mom and I are having a disagreement about the color of vest and ties. My groom is wearing ivory as that's the color of my dress. The groomsmen are in eggplant. The woman at the tux store said most fathers do black or silver ties and vests so I chose a dark charcoal silver kind of one. My mom wants the fathers to wear purple. I said I'd take it to the message board and let you guys decide. So...What did you do?
