Anyone who is specified on your RSVP page is welcome!
If your RSVP offers "and guest" then yes of course, if not, then we would rather it just be you sharing our special day with us.
Business Casual Attire: Sundresses, blouses with skirts or dress pants, button down shirts, and slacks. We are pretty relaxed people, so what you'd typically imagine wearing to a wedding should be fine with us!
