I was looking for jeans similar to styles I had previously purchased at American Eagle and came across these.  I bought two pairs.  For reference I'm 5' 3'' around 130 lbs.  I bought a size 6 short and it fit perfectly though I did have variations between the two pairs in the exact same size.  The material I wouldn't call actual jean/denim because it's rather thin, but it's very soft, stretchy, and comfortable.

The mascara color I bought, was noticeably more loose in the legs compared to the other color which was called Janice.  The Janice pair fit like a glove, and the Mascara had more give in the leg area.  I ran into the same exact problem with American Eagle pants as well, so maybe they are made at the same place.  If the Mascara color doesn't shrink up a bit in the wash, I plan on taking in the legs a bit.  I like a fitted feel in a style like this which are almost like jeggings, not pants with extra give in the legs.

Regardless, I really like these.  Other than the minor leg problem with one color, both pairs were a perfect size for me, look really nice, and feel great.  I would buy more.
