Alo seamless ribbed cropped serene short sleeve

Alo seamless ribbed cropped serene short sleeve top. I am unaware of the size because there wasn’t a tag inside when I bought it. I had bought it new at a second hand store and the tag was a small (4-6). I’ve worn it one time and it’s just sat in my closet. Would love for it to go to someone that finds joy in wearing it.
