I never knew I could love a pair of jeans so much. I went with a size 2 in these (I'm 125 pounds, 26" waist, 38" hips) and they are comfortable without being too roomy or sliding around. Unlike the Decade Bonnie jeans (I'm a 28 in those and love them for other reasons), which are also 100% cotton and had a lengthy break-in period, these were comfortable to wear almost immediately. Although I could have potentially worn a size 0 based on other reviews, I'd stick with a 2 personally as I wouldn't want the rise any shorter and I like being able to wear long underwear underneath. I wear these 2x a week and am looking for a second pair come spring. Although I didn't measure these when I got them, I don't feel as though they've stretched out at all.
THANK YOU for making magic pants that fit us folks with a significant waist to hip ratio, you've made me love jeans again :)
