I have owned Dickies products for years and have always found them to be great work in yard/weekend pants but I forgot that they run small, very small. The label stated that they were Original fit or something like that so I figured since I had loss 10 pound they would fit but be snug. Nope, I couldn't even button them.  I advise you purchase 2 sizes less, i.e. if you wear a 38, buy a 36.  Dickies are a quality product but when other companies started increasing pant sizes to make men feel better about being overweight Dickies didn't get the memo, which is OK by me.  I'll just have to order a size up and hope that fits.
