Cocktail, 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.
If your invitation says the name of your significant other or "guest" then yes, if not, we would prefer if it was just you.
We would love to celebrate with your entire family, but unfortunately, our venue does not allow children under the age of 12. We ask that only those invited attend the celebration.
