This sweater is warm and so comfortable. It's long - covers my bum and I'm long through the torso. It washes well (I put it in the dryer even though it says hang to dry. If you hang it, it takes forever to dry and I couldn't wait that long to wear it again). I would say this is a casual sweater. Some other reviewers have said they wear it to work, so I was hopeful, but I work in a professional office environment and I wouldn't be able to get away with this at work. I normally wear a XS or S. in this, I ended up with XXS/XS. The S/M was way too big.
