Party in the back. There's so much to love about this dress: the maxi length, the body-conscious fit, the ultra-soft ribbed fabric, and the backless design with slider tab details. Crafted in our best-selling Sculpted fabric, beloved for its high-stretch and contouring effect. Fit & Flare: Fitted bust and waist with a flare skirt. Boat neck. Pull-on design. Unlined.
