As others have stated, these vary wildly in size. I ordered 3 different colors, ALL in size 13. The mint green are the roomiest, slightly baggy in the front, and right on the threshold of being too big overall! I might return them. The coral color was slightly smaller. The burgundy ones are a full size smaller-fitting and actually gave me a "muffin top." I'm 5'4" tall, have 39 inch hips and typically wear a size 11 in jeans. My overall clothing size is M/L. (XL, if I want a roomy fit). After reading reviews, I ordered one size up from what I normally wear. My butt does look nice in these, but I'm concerned that the fabric will stretch out at the knees, which I hate. These feel stiff brand new, but they might soften in the wash. The length is perfect for my height.
