We love your kids- we really do. However, our wedding is going to be an adults- only evening. We greatly appreciate you making arrangements ahead of time so that you are able to celebrate with us.
If your invitation says "and Guest", then yes, if not, we would prefer if it was just you.
The dress code for our wedding is semi-formal/ cocktail attire. Ladies should wear cocktail dress/pantsuits, and the gentlemen should wear a suit and tie or a sports coat.
