ZARA Ribbed Knit One Shoulder Body Con Dress Black Gray Wash Raw Hem size 0

New without tags body con dress from ZARA. Tagging says it’s a medium but is very small. Lots of stretch though. The waist stretch’s to 16 inches lying flat. One shoulder style and fabric is a ribbed knit. Color is a distressed black. I would say size small or xtra small. Thanks for looking and happy Poshing! Make an offer!
