Shoulder-baring black and white, knee-length dress

Figure-hugging back and white patterned dress, with zipper back and 2 buttons at neck. The bust opening has been professionally sewn shut as it revealed a lot of cleavage. The label says it's a size 12. However, I wore it as a size 6/8, and it wasn't loose (see pics). The fabric is a little giving, but not a lot. Unlined. Length is 36" from shoulder to hem. Short 3" slit at back.
