We love your kids- we really do. But we want our wedding to be your night off! If you still need to bring your kid(s), please let us know in advance.
If your invitation says "and Guest," then yes, if not, we would prefer if it was just you.
Semi-formal, please. But we want you to feel comfortable, so if those heels are too high or that top button is too tight, let it all hang loose!
