We have decided to go 'Caribbean Casual.' So, yes, your unbuttoned Hawaiian shirt is acceptable.
We do not have one! We have been living together for over a year, so we really are not in need of the traditional registry items. We know traveling out of the country is a larger expense on our guests, so gifts are not needed. If you must insist, we will be accepting cash, Lowe’s gift cards, or Venmo that will contribute to finishing the hardwoods in our home.
