I'm 5'7" and around 154#. I purchased a 28 and 29 in both colors. I ended up going with the 29 in both colors because of the length and more "coverage" when bending over (I mean, they are low rise jeans...). FYI, the lighter wash runs smaller than the darker wash. I could have easily worn either 28 or 29 in the dark wash, but I couldn't even get the light wash 28's on.
