Hi, I have a man of honor in my wedding (my brother). The groomsmen are all wearing black vests and green ties to match the bridesmaids. I was going to have my brother wear a black vest and pink tie to match the flower girls. My FH is wearing white vest and white tie.... I'm wondering if it is inappropriate that my brother wear a different color tie than the other groomsmen/best men, seeing as he is not the groom and the groom should be the only one who stands out? Or is it OK since he is on my side?
