I'm not what you would call a "skinny girl", but I read other reviews and had to give these jeans a try. I am close to 5'7 and weight about 170...165 on a good week. LOL! But anyway, these jeans fit perfectly. I ordered a size 13 and they fit like they were tailored for me. My stomach is completely flat and I tend to carry most of my  weight in my hips and thighs. These jeans weren't tight on my thighs and made it look like I had a bum to die for (i.e J-lo, Kim Kardashian). To begin with I have what most would describe as a curvy figure and an average hip to waist ratio. These jeans are great for anyone who is 1: curvy and looking looking for jeans that are not tight on the thighs and 2: for someone who wants to maximize the shape of the gluteus maximus. These jeans don't flatten the back area like many "skinny jeans" on curvy girls can do. I recently turned 30...my husband LOVES the way these jeans look on me...I get many compliments from other females and they want to know where to buy these jeans. The lenght is perfect, I can wear them with flats or heels. Oh, btw I usually wear a 12 in Levi's Perfectly Slimming Jeans which I also love. Best of luck during your shopping experience, hope this helps.
