I actually really love this hoodie. It was exactly what I was looking for: A very thin, stretchy, summer hoodie. It's not meant to keep you warm during the winter months. Also, I disagree with many reviewers on the sizing issues. I am 5'5 and 120lbs. I first purchased a large based on other reviewers stating that it was necessary to order two sizes up. It was too big. Not overly so, but not as form fitting as I wanted. I ordered a medium and it's perfect. That being said, the medium is a tight fit. This hoodie is made out of very stretchy fabric. It's meant to fit tight! With this sort of fabric, a looser fit is going to end up looking saggy. I would say, if you're normally between a small and a medium, go with the medium. Between a medium and large, go with large... etc.
