My fiance and I both have 5 people on our sides of the wedding party and my brother is marrying us. The groom's sister is going to have the only non-religious reading in the ceremony. My brother will be wearing his army dress blues, the bridesmaids will be wearing long chiffon champagne colored dresses and the groomsmen/best man will be wearing light/medium grey suits. How do you suggest we coordinate the sister of the groom's attire with our wedding party? Should she match my brother who is marrying us and wearing navy? Should she stand alone in another coordinating color? I want there to be a distinction between the bridesmaids and the ceremony readers. On top of what she's wearing, also, should she take a seat at the ceremony until she does her reading, or should she also be standing up there with my brother because it will be a very short ceremony? Any suggestions would be fantastic!!
