As fancy as you want, there is no dress code. Think summer cocktail/semi-formal/dressy-casual. Though keep in mind part of the night will be outdoors so if you are going to wear heels you might want those things that help you walk in the grass.
Once we have most of the RSVPs in we can determine if there is room for a plus one for you. As the date gets closer, feel free to ask us. Just don't be a dick if we say no. :)
Maybe - we would have to figure out the logistics. If you would like to attend virtually, let us know so we can set something up.
