My fiance is having his sister as a groomsmen. The problem I am having is what to have her wear. The groomsmen are wearing Navy Blue jeans, cowboy hats, white button up shirt, and boots. They will have a matching tie/vest to the color of bridesmaids dresses which are all different colors. (We have 4 on each side so 4 different colors) What do I do for my fiance sister?
