Lulus Exclusive! The Lulus Straight To The Heart Black Backless Maxi Dress has stolen a special place in our hearts! Medium-weight stretch knit shapes this head-turner of a dress with a rounded neckline and princess-seamed bodice with a strappy open back. Darting at the waist creates a tailored fit atop a figure-flaunting maxi skirt with a mermaid hem. Hidden back zipper/clasp.
