I purchased these for my tall, slim husband.  He lost his little pot belly a few months ago and needed better fitting jeans.  I ordered the size I wanted, 35, and a larger size, 36, because I read reviews saying the waist ran small (it doesn't--sent back the 36).  I especially love being able to get the longer length, 36", because it's hard to find lengths over 34" in stores or online.  I only wish there were more in stock, or that I could back order them.  He needs a few more pairs for work.
