I am retired, so I wear lounge pants a lot. I ordered XX size. They are not XX size in the waist, but I can wear them because of the elastic in the waistband. The other concern is due to a combination of material and design. They are fine when standing but when you sit down, the legs draw up way more than any of my other pants. I fixed this by using a large safety pin to attach the pant leg to my socks. That is not a good solution, so if you are 5' 11" or taller...these will not fit properly when you sit down.
