It is my sisters wedding and I have been given the responsibility to arrange corsages and boutonnieres for everyone but I don’t know who wears it and for how many people I have to arrange it. I have seen many weddings but here I am in doubt. I want to know do I have to count the other family members as well like the organizer and the ushers? Is there any rule of thumb which I should remember? I don’t want to end up giving it to everyone so please tell me who are the people to whom I shall give this?
