If it is not because of work, too thin and too long skirt, you should pay attention to your walking posture. Wear a one-step skirt and don't stride. When you go up the steps, you must walk sideways and turn your legs horizontally. You can try how high and how low it is without affecting the twist of the skirt, and walk at a good pace. One-step skirts are different from other skirts in slimming. If you are satisfied with slimming, then keep walking unchanged. It should be a small step and a quick fall.
