Zara Black Backless Satin Top. Size Medium

I bought this beautiful Black Zara Top in London this summer. It's gorgeous, but not for me. Material is polyester with a satin, silky feel. The back is open with a large band bow tie at the bottom. The front comes up to the neck. It's true Zara style which I love. Pit to pit is 17½ inches. Length is 20 inches. Never worn. The small thin band across the back on the right side broke away, so I sewed it back, photo shows this.
