Our colors are navy (groomsmen) and burgundy (bridesmaids) and since the mothers will be wearing dresses, I prefer they aren't burgundy and clash with the bridesmaids. I think navy is an okay color, but do I actually get any say in what they wear? I want everyone to be coordinated because we will be doing family photos so to some extent I do care, but when it comes to mothers and grandparents, how do I politely ask them to stick with our theme? Or do I choose a different color all together for them?
