For women, a dress paired with dressy shoes is perfect. Men should wear a dress shirt and pants. You may wear a suit jacket or tie but it is not needed.
For women, a floor-length gown or dressy pantsuit. It'll (hopefully) be a warm, sunny evening - so feel free to lean into brighter colors and floral garden-vibe patterns. In addition, much of the event is on pebble, gravel or grass so please choose your shoes accordingly. Men should wear a suit and tie - preferably black, gray, navy or brown.
