The fabric is so slick, and the way the skirt's attached doesn't do much to hold it in place.  I've gotten other skirt/capri combos at sporting goods stores that are much better than this.  I don't know why they chose such a slick shiny fabric--yuck.  You can't tell it from this picture, but it's shiny.  And nothing looks more ridiculous than a skirt halfway up your tooshy while you exercise.  I couldn't concentrate on my workout, I was too busy pulling my skirt down or worrying that it was up too high.  They should've sewn it better.
