LOVE!!! I never thought I would look this good in jeans I bought on Amazon. WOW. I bought the 3 and the 5 so I would have a pair in case I was a couple pounds difference in water weight. For reference, I am 5'0 100 pounds 35 hip and I bought the 3 in dark denim first then the 5 in medium denim. I am surprised that bigger ladies fit the 5 but all the power to them if they do. These jeans do have stretch. I cannot handle pants that are exceedingly tight and I can tell you that the 3 fits tight on my butt and legs with my measurements. Also, there isn't a huge difference between medium and dark denim. Happy shopping chicas!
