Cocktail attire! Think tea-length dresses or a blazer and dress pants.
If we don't need you for photos (looking at you, family members and bridal party!) please go enjoy Chicago! The venue is right across from the Art Institute, the Bean, and Lake Michigan, alongside tons of other museums, historic sites, shopping, or even restaurants/bars (though we promise to have plenty of food and drink for you throughout the evening)! Nothing would make us happier than to hear about your Chicago adventures during our wedding weekend. (Though we would also be perfectly happy to hear you took a restorative nap back at your hotel.)
