Ok i haven't even heard of this until recently but how does it work in terms of showers? I think it is EXTREMELY rude to invite people to your shower but then not invite them to the wedding. Do you invite all the people on your A and B list to your shower? What happens if you end up not inviting the B list? I am probably NOT using a B list but I do have a bunch of older people in my family (Great aunts/uncles) That I KNOW will most likely not be able to travel to the wedding that I will invite because they are family but can then invite more friends if they RSVP that they cant come.
