Black yoga Athleisure shirt M

Black yoga Athleisure shirt M in very good pre-owned condition. see photo for one loose string on front (pic with pen point for reference) Flowy black soft yoga tee. has a scoop low neckline on back with a strap across the top. Great for layering or working out. Size tag is missing. however I believe it is a medium. ( I bought it new but def check the measurements - i feel it's meant to be oversized) Cap sleeves P2P @ 21.5 @25" long from neck strap to hem on back. hem is slightly rounded.
