Long gray knit top w/ crochet like design on back

Gently used, worn very few times, I took good care of it as I loved it so much. Bottom part is worn ruched or folded. I’m 5’1.5” so good for someone around that height. Wear with leggings or skinny pants/jeans. Black tank not included. That’s how I used to wear it. Those familiar with foreign sizes, it is 155/80A To me, feels like XS
