As much as we both ADORE your children, we want Mom & Dad to be able to let their hair down and enjoy the night! Make use of a good babysitter and come have a good time celebrating with us! :)
If your invitation says “and Guest,” then yes. If not, then consider it an opportunity to meet some new people. ;)
Cocktail, please. However, 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. You may want to consider bringing a sweater too as it will likely cool down in the evening. Ladies, don't forget to bring a comfortable pair of dancing shoes too ;)
