Pack for variability.
The weather out west is fickle. We've seen it go from 90 degrees to 30 degrees in a span of 6 hours. Because the end of May is still considered winter in this area, be prepared for some chilly mornings and evenings.
Please bring something nice to wear!
You do not need a uniform, suit, or gown. Men can wear khaki's and button downs (short sleeve or long sleeve) and women can wear maxi dresses or long rompers. These will be low key, candid pictures for the most part.
