I first ordered these Pants in my "Normal" for other pants size 32x32. But they were a bit too small for me so either I am fatter or they run a touch small. Either way I sent them back, free shipping which was cool, and they free shipped me a pair of 33x32's. These fit very nicely, so I bought another pair (33x32) a week later in Heather Gray. I'd say there is definately a 1/2-1" difference in waist size (so almost like the 32x32's I had ordered dfrom the start). They fit well... Maybe a tad snug, but I am working on losing 5 or so lbs so they should be perfect in a month.
In the meantime, I bought a pair of Striped D2's off ebay. And they turned out to be a little larger in the waist than both of the Amazon orders.

So again, the pants are great. Nice and sturdy fabric, look nice, great price in my opinion; but be aware you may have to do some back and forth in sizing to get what you need.
