My measurements call for the medium but the small fits best. Has some stretch to it so size down for a more fitted look. Also, it's not really sweater material because the back of the material looks like terry cloth. I have sweats made from this stuff! Still, it's fairly comfy but more of a fabric shirt than a sweater.

My measurements have me on the cusp of a medium and large. Went with the medium and I still find it a bit too large. I just ordered the small, hoping that will work. It has stretch so order a size smaller if you want that fitted look.
