I'm 5'6 and wear a size 20. I wasn't sure if I should get the 2xl or 3xl. I got the 3xl and I'm happy. While they are a little loose around the waist the drawstring is great and secure. I think sizing up gave me a looser leg look and I'm perfect that. I wish the pockets were a little deeper. If the seam is 7 inches long the angle for access only allows about three inches of actual depth. So be careful with your valuables because I can see your items falling out. I wish they were a little shorter but I can hem them. The material is comfy and I'd say a medium weight. I don't agree with the other reviewers saying it's thin. But that might also be because I sized up and the fabric hangs instead of clings. I see these becoming my new lounge around the house in summer pants.
