Soooo comfy! I'm waist size 31. I was debating the XL or L, but Large fit just fine. They looked a bit small out of the package, but once I put them on I noticed they were super stretchy.
EDIT: Knocked down some stars :( The threads started coming undone really bad down the butt area and left calf. I tried sewing them myself as best I could to save them though! Still wear them to lounge around at home
