Off-white ribbed cropped lace up tank

Ribbed lace up tank from ASOS. I love the ribbed, slightly thicker sweater-like material. Worn only a handful of times, no signs of wear. The tag says size 12, but I think that is British sizing. I’m not sure what the actual US size is, but I’m a small and it fit me, I think it would be good for a small/medium. Bundle with another item in my closet labeled “💕2/$20💕” and make an offer of $20 for both! I will accept!
