WHY WE LOVE IT The Cosima Nap Dress® is easy, breezy, and totally chic, featuring a fully-smocked (and bra-friendly!) bodice and a crisp, high boat neck fit. You can wear Cosima with flat sandals for a quick out-the-door look, or add a belt and statement earrings for a little something extra. About the Fabric Tonal Seersucker is lightweight, textured and, perhaps most importantly, wrinkle-resistant fabric. Fully lined.
