I am only having 4 bridesmaids and of those 3 of their parents are invited to the wedding because I happen to be close with all of them. For the other bridesmaid I am not as close with her parents so I didn't invite them. I have known her since high school and have met her parents a handful of times but I am not close with them. Would it be rude to not invite them? Should I just add another 2 to the list?
