We picked out tuxes the other day. GM are wearing vests and ties to match BM dresses. FI is wearing ivory vest, shirt, and tie (as I am wearing ivory.) We realized today we forgot to change the color vest and tie for my brother so right now he would be in a blue vest and tie, which I do not want. We are going to call the tux shop. I want my brother to wear black vest and black tie and ivory shirt. My sister in law thinks that is too much black. What do you guys think?
