H and I are going to his friend's wedding this weekend. The invitation says Black Tie Optional and is at a really fancy place in Manhattan. The problem is that the marriage ceremony is at 3:30pm so we have your typical Catholic time gap because the reception doesn't start until 7pm. Am I right in thinking that he would have to wear a suit to the ceremony since it's in the afternoon? Then change during the gap into the tux for the evening reception? That seems like a lot of trouble, but I still kinda want him to do it.
