Attire: Fancy-ish to Festive Think of the dress code as Mountain Formal meets Celebration Mode. Gowns, tuxedos, cocktail dresses, sundresses, sport coats, nice shirts, party clothes, and even classy shorts are all welcome. Basically, if you look in the mirror and think, “Yes, I could happily celebrate love and dance in this,” you’re doing it right. Come fancy. Come festive. Come comfortable. And remember…the only thing you shouldn’t wear is regret that you didn’t dance.
