I am 57 130 lbs. I purchased size 5 in the dark denim. They fit like a glove and the length is PERFECT (can wear with flats or heels). These are light weight, which I love, soft & comfy, perfect amount of stretch. I have a hard time fitting jeans, so I was pleasantly surprised at these. And you cant beat the price. So I purchased another pair size 5 in the next color lighter and they actually fit a bit better. The dark blue are more snug, probably due to the dye. I may order them in black one size bigger (7) just for comfort sake, as they are nice and stretchy. Definitely my new favorite jeans.
