Black flutter sleeve top by Zara

Size M (the brand and size label around the neckline have been cut off because they were scratching the back of my neck 😞). Included pics of the other label inside the shirt that has fabric composition and proves it is by Zara :) Black. Front slit in upper chest area. Did not have much trouble with it opening up and showing too much of my cleavage :p haha. Single button closure at the back. Ties around the waist. Super elegant with the flutter sleeves. Worn out ONCE to a dinner in NYC.
