I got a cropped sweatshirt in Medium, and it arrived quickly. It fits very well. The neckhole is small, though, and it's hard to get it over my head, but once it's on, it's on. It has a sort of shelf-bra to it that gives it a comforting tightness and sense of security - it won't be going anywhere. It goes great over a dress because the fabric is good quality, thick, and doesn't show the layers underneath.
Everyone in my family hates it when I wear this shirt, so obviously I'm going to wear it to Christmas.
