If your invitation says "and Guest", then yes, if not, we would prefer if it was just you.
Cocktail attire: Wear cocktail dresses, little black dresses, dressy jumpsuits, and dark jackets and slacks; no jeans or sneakers are permitted. We want you to feel comfortable and respect our attire request.
We love kids - we really do. However, we want our wedding to be your evening off.
