When dressing for a jazz dance class, think about wearing clothing that allows you to move. Jazz classes are casual and relaxed, so feel free to select your own clothing. A dancer's body lines need to be visible, however, so baggy clothes are generally discouraged. Tights and leotards are fine, but most jazz dancers prefer to wear jazz or dance pants. Jazz pants are usually boot-cut or flared styles, as tight bottoms would restrict ankle movement. Tops usually worn for jazz include form-fitting tank tops, t-shirts or leotards. Check with your teacher before buying jazz shoes, as many classes have preferences.
