There are a lot of descriptions of "wedding attire" out there. After much Googling and debating, we're going with "Cocktail Attire" for our party. There's indoor and outdoor space, and it's a fall evening in Oregon--you might consider a jacket or scarf, depending on weather.
Doors open at 5:45. Headliner at 6:15 (around sunset). No opening act!
Adults only. We appreciate being able to spend our time with the grown ups and not keeping the kiddos out of the poison oak surrounding the property.
