This dress features a mermaid silhouette that showcases a feminine, curvaceous beauty. The subtle shirring on the back creates a defined, shapely style. Delicate shoulder straps add a touch of girlish charm. A roughly cut back slit adds a touch of sophistication. ★ The back has elastic. ★ The length of the shoulder straps can be adjusted with the adjuster. I purchased this in August of this year but am selling it because I haven't worn it.
