I was also afraid that this would fit small so I ordered a size larger. It fit, but the legs were although snug, it didn't have the right tight fit so I exchanged it for my normal size. I am very petite and am pretty fit and I found the material really stretchy and comfortable. I absolutely love these pair of jeans!
I was a bit worried that these pants would fit small, based on others' reviews and the fact that they are coated denim. However, when I received them, they fit really nicely. They are a bit snug in the legs when pulling them on, but once on, they are very sexy but can be dressed down for work. I hope to get a lot of use out of these pants, as I have been looking for something skinny yet work appropriate.
