Please wear cocktail attire :) if you need some inspo, check out the links below.
Weather: It will be warm out during the day (80s) and then cool off to the 60s-70s at night. You may want to bring a sweater or shawl if you tend to get chilly.
Please note: Since part of the ceremony and party will be on grass, it is recommended to avoid high heels/stilettos that will sink into the grass.
