I am thinking about designating Black Tie Optional on our invitations (I'm guessing I do this on the reception card, and not the actual invitation?). Our wedding is going to be formal- the ceremony is at a cathedral and the reception at a nice hotel, my dress is very dressy and my bridesmaids are wearing floor length dresses.My only concern is that I may isolate some of the groom's family- they are not from this area and I worry they will think this is a snobby wedding. What do you think? And do I put the designation on the reception card or the actual invitation? Thanks!
