Men can pair a short or long sleeve button down with nice pants and comfortable shoes. Sports coat optional. Women can opt for sundresses or flowy pants with a nice top paired with sandals.
Men can opt for a suit, tie optional. Color of suit does not matter. For women, try a mid-length or long dress. While it will be May, the evenings do get chilly so bring a light sweater or shawl. Avoid skinny high heels as much of the venue is grass or gravel - go for wedges, block heels, or flats!
