They're very stiff, so not that easy to measure. If you do the BIG method and pull the waist out to full width, I wouldn't be surprised if you got the same measurement I did. I also wouldn't be surprised if they were a bit inconsistent in sizing (I think the BIG site says as much). yep I pulled it out end to end, keeping the front and back tops of waistband even...my size 31 measured a few cunthairs larger than 31 but less than 32. Def nowhere near 33. And yea they are REALLY stiff, like cardboard. I did a cold soak and after it was dry I was afraid the legs would break off.
