They are not. Vaccines and masks are both optional. While we recommend a mask if you are not vaccinated, the choice is totally up to you.
We love your kids—we really do. But we want our wedding to be your night off! So besides the wedding party children, we are requesting no kids attend this event. We have hired a few honorary guests to "babysit" the children for the event should they get restless.
If the paper invite you received in the mail said "and Guest" on it and/or if your online reservation has a "Guest" tab then yes, if not, we would prefer if it was just you.
Formal/Cocktail, please. Let this be your night to dress up! No jeans, ball caps, gym shoes, etc. 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.
