While we truly love your kids, we want you to enjoy our wedding day and have the day off. Please be sure that you have made proper arrangements for your kids.
If your invitation says “and Guest”, then yes. If not, we would prefer if it was just you.
Cocktail attire, please. But we want you to feel comfortable as we know it may be warm that day, so if those shoes are too high or that top button is too tight, let it all hang loose.
