Yes we are, but we like all of you so much and we really want to bring everyone together to celebrate and pretend like 2020 never happened (except for the part when we got married, obviously).
We've decided to make this wedding adults only so that everyone can cut loose and enjoy their night off!
If your invitation says "and guest", then yes. If not, then we would prefer it was just your wonderful self.
Formal attire is strongly preferred. For women this means cocktail dresses and for men this suits.
