Beautiful Zara full skirt spaghetti strap black sweetheart neckline dress

Gorgeous spaghetti strap dress with tons of fabric full circle skirt (bit wrinkled in photos bc was stored but is in pristine condition - never worn bc tight on my bust 36C). Side zip up backless (similar to front neck line except straight across in back with nice button detail for show). Measures 15” at empire waist and 16” pit to pit
