We started wearing kilts when my boys were small. We attended the Mormon church then which although doctrinally than a baptist church it is a politically conservative church. Many in the congregation said how great they looked but the bishop (the head of the congregation) called them in and told them not to do it again. That isn't church wide though. I have worn it since then especially when traveling and got compliments when I do attend. The difference may be visitors are given a much greater leeway but I know it's not an official ban
