Loose fit sweatshirt on me at 5'1, 33" chest, and 118 pounds wearing a size small. The silver zip-up makes it more dressier than a typical sweatshirt. It's not thick, but it's not also too thin. I washed and dried it and didn't notice any shrinkage. The zipper slides smoothly.
Love the style, the weight and the length. Would consider buying another if I find a deal.
