Summer formal. The wedding is a glass building on the summer solstice, so dress for warm weather.
This is the midwest, which apparently means that things start timely. Please arrive at 3:30 and expect the wedding to start soon after.
The reception will end around 9:00pm. The marriage should last longer.
Yes!
Parking is generally along the roads, or at a parking lot in front of The Muny theater, about 200 yards away.
