Due to space restraints, there are no plus ones unless specified on your invitation. If you requested a plus one but did not see one on your RSVP, please allow time for declines to come that may open up space for your guest.
Unfortunately, there are no children at the wedding with the exception of the wedding party.
Black Tie optional attire means that formalwear is preferred, specifically, suits, ties, tuxes, and gowns. However, if you have a nice dress or suit that doesn't exactly qualify as "black tie" you are still welcome to wear them and look your best!
