Do not get the DP one. I got it and it's awful, really bad quality, shiny cheap fabric. The elastic waistband is too thin so gets squashed when you sit down and stays like it, and the hem fell down after two washes.
I have the asda one too- tis very good, but not very high on the waist.
I have an Isabella Oliver one, the "Marilyn", I believe. I got it at a good reduction in price, so if there is an IO one you fancy, watch their sale. It looks very tight and fitted and my DH said, "How impractical!" when he saw it. However the material is so stretchy I can do high kicks in it. So I would say that stretch is a key point when it comes to making such skirts comfy and wearable. The waistband is very high by the way.
I have a Boden velvet pencil skirt in which I have lived this winter. It has wonderful stretch but a lower waistband. It is currently unavailable but there is a good reduction in the sale should any returns or mysterious new stock come in.
