My future mother in law picked a dress color (grey) that might clash with the wedding scheme (yellow and brown). The groom and groomsmen are wearing brown, I'm wearing champagne, and the bridesmaids are wearing yellow. My mom is wearing a rust color dress. Should the dads be in a different color suit? Black perhaps? I actually love her dress and wouldn't want her to have to change it, the dad's are easier to change. Any input??
