Respectfully, we have chosen to make our wedding day child-free.
If your invitation says "and guest", then yes, if not we kindly ask you to just bring yourself.
Semi-Formal: Tuxes and gowns are welcome, and so are suits and cocktail dresses. But 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 ... But not too loose ;)
