I am 5'7", 170 pounds, and I purchased size 14. This is my first day wearing them so I'm not sure how they do in the long run yet. So far, these are the best slacks I've ever boughten!! I purchased the Oatmeal color, Stone, and Black. They are by far my favorite pants to wear. They fit perfectly, the colors are as expected, and they are extremely comfortable!! My only problem is that they are too long, which is a first for me because I am a little tall and most pants show my ankles. These pants cover my shoes and I keep stepping on the heels. These pants are stretchy, do not bother me when I am sitting or standing or even running, they do not slide down or ride up, they stay in place and hug my curves. I'm already looking at more colors..I'll be buying more soon!!
