I took a Large. The Dark Moss color was such a pleasant surprise. The material has a nice sheen to it. This is a long tank, beware of that if you don't like longer tanks!
Fit Fam says this one runs small since it's a fitted, ribbed style with more structured material, so most size up for a comfier feel. Think polished basic that hugs the body rather than a loose, drapey layer.
