These are one of a kind sport-Tek fleece jackets. They have an approx. 8 1/2" zipper, so plenty of room to put over your head. What makes them one of a kind is they are hand painted and just every one of them is cuter than the next. They're just so hard to choose which one. They do run roomy, so plenty of room if you are going to put over something. Each design that is on the front is on the back as well in a smaller version.
I went down a size and then I could go down 2 sizes if I was going to wear it as a top without anything under it. I had plenty of room in the back, in the stomach are and around the bottom. It has a collar that you can pop up or fold down.
