Cocktail attire, dressy but not black-tie. Think cocktail or midi dresses, dressy jumpsuits, or a polished skirt/top. Suits or dress pants with a button-down (tie optional). Since Arizona weather in October can be warm during the day and cooler after sunset, we recommend light, breathable fabrics and bringing a wrap or light jacket for the evening. Whatever you wear, we're sure you'll look great!
