The Prana Women's Opal Dress is stretchy and soft for summertime wear. Casual wear that is ready for just about anything. Travel days and weekends at home, family picnics and nights in the city. The polyester and spandex blend wicks moisture in the heat and stretches for movement. The v-neck flows into a racer back with an internal shelf bra for light support. Falling to mid thigh, you'll be relaxed and comfortable all day long.
