Semi-formal please. 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.
If your invitation says “and Guest,” then yes, if not, we would prefer if it was just you.
We prefer an unplugged ceremony. We hired a photographer to take pictures and we prefer to see your faces, not your phones! However, after we seal our love with a kiss and you may take photographs.
