I ordered the medium size, which is what I would normally wear in a legging. As far as body type, I have quite a few extra pounds in the stomach area, but skinny legs. Im pushing 60, so they were a tad bit shorter than I would have liked, but fit well in the legs. They were tight fitting, just as youd expect. When I was putting them on I felt like they were going to be exactly what I was looking for... and then I noticed an issue. They were baggy in the back of the knee!!! This is just not something I could deal with, but I don't think a smaller size would have worked either due to my height/weight. I just don't understand why the knees wouldnt have been as tight as the rest of the pants? The manufacturer definitely needs to do some reconfiguring because this is just weird. I sent them back and don't think Im going to take the chance to order another pair.
