I am 5’8”, approx 153 lbs and I ordered a 29 in these. I do enjoy the relaxed fit, I will say that the crotch area sits a bit low and did cause some discomfort, unpleasant bunching. These were also a bit buggy under the bum. Overall, they are comfortable, I do like the length inseam wise. I DO enjoy these pants.
The jeans are fantastic for me. I don't like the look of skinny jeans on me. I do not work out, but have always been thick-thighed and large bottomed. The are a great rise for my mommy belly and I love the loose fit.
