I can't find my order information, but I'm pretty sure I got a medium, and I'm also a medium in boxer briefs. I know I double checked with the measurements on the site. Mine fits well and was what I expected. It got more comfortable when my leg straps stretched out a bit, I think they were a little short for me. Just be careful not to twist the leg straps, they're thin and they're uncomfortable if they twist. If they're flat, it's pretty good.
