I was pleasantly surprised by how much I like this sweater. The M fit is is spot on. 5'5' 140 lb, over 70. I also ordered a L but it was way too big. The shaping is a bit boxy,. That is why I gave it 4 stars. I wish it did have a little bit more shape. However, I bought it to knock around the house, so it will do just fine. It is even nice enough to wear out casually -- that said it would have been perfect with just a bit of shaping. after a few wears, it has washed up very well. Washed on gentle cycle, and air dried. Happy.
