Assess what kind of skirt you will be wearing. If possible, choose skirts made of flexible, lightweight fabric with elastic waistbands. Hem skirts that drag along the floor to prevent you and your fellow dancers from tripping.
Choose undergarments that will make you feel comfortable and covered especially if you will be jumping, kicking or rolling on the floor. Tights, leggings, shorts or bloomers can be worn under your long skirt while you dance. Wear two undergarments together, like tights and shorts, for extra coverage. Some dancers wear long, loose pants under their skirts.
If you are not used to wearing skirts while you dance, ask your teacher if your can first learn your dance steps or choreography without wearing a skirt. Mastering the movement ahead of time will help you feel more relaxed and confident when the time comes to add a long layer of clothing. As you rehearse, think about which movements you will need to adjust to accommodate your skirt.
Practice your dance many times while wearing your skirt once you've mastered the basic movements. Get used to the weight of the fabric and the way the skirt hangs and shifts as you move.
Dance forms like Flamenco and Folklorico automatically incorporate dramatic flourishes of the skirt into each step. Even if you don't practice these dance styles, using your skirt as a prop can add an extra dimension to your dancing. Holding the ends of your skirt above your ankles also frees your legs to make it easier to perform many dance steps.
If you or your choreographer prefer that you don't accentuate your skirt by using it as a prop, experiment with ways to subtly lift the long material out of the way during challenging steps. For example, if the skirt constricts you as you leap, coordinate your arm movements so that you can gently lift the skirt away from the floor as your prepare to jump.
