I've been looking for a pair of micro fleece pants that are not run of the mill. These are light weight but warm. The piping on the side seam and waist band is attractive and adds a touch of class to what otherwise would just be another pair of sweat pants. I am very pleased with this purchase. I normally wear a size 2 so I ordered the small. They fit a slightly big by about an inch, more of a relaxed fit, but they aren't offered in an xs so I am definitely keeping them. This probably makes them run true to size. On the model they look like they are very low cut but I am a petite size and short waisted so they fit me right below the belly button but come up high enough in the back so no "butt cleavage" is exposed. Over all this is a great purchase and I am extremely pleased!
