We really, really love the kids, but we would want this night to be a night off and let loose. We will only be having the kids from the immediate family coming. We hope you guys understand and we really hope you could make it!
If your invitations says, "And Guest" then yes, if not, we would prefer if it was just you.
Cocktail or Formal please. But we want you to feel comfortable, so if those shoes are too high or that top button is too tight, let it all hang loose.
