FYI I am 5'5' and 115 lbs. and I got size 28.
I actually really like these. They look really good. They're a bit shiny but not extremely shiny, so they don't look like plastic- they are a pretty good leather imitation! The material is thin; the inside is a really smooth surface that makes them very easy to pull on, and they have just a little bit of a stretch to them. The reason I don't give them 5 stars is that the fit is a little bit off. They're definitely bigger around the top than through the legs. The waist is big on me, while the legs are really tight, and my legs are pretty thin.  If you have thicker legs, these will probably be uncomfortably tight around the knees, where you have to bend, and around the calves. My calves are very small-- like high boots are always too big around on me-- and these are tight on my calves. These will fit better on someone with relatively thin legs and larger waist/hips. Still, I'm keeping them because the fit issue is only slight, and won't be noticeable with a shirt that covers my waist. And other than the large waist I LOVE the way they fit! At 5'5" the length is perfect for me.
