According to the little red book, there are several ways to dance to cover your belly button:
1. Clothing choice: wear high-waisted dance clothes or tops to cover the navel. Choose close-fitting and elastic clothes to ensure that they will not slip or be exposed when dancing.
2. Use close-fitting clothes: wear a close-fitting vest or underwear to cover your navel. This kind of clothes can effectively protect privacy and provide additional shelter.
3. Belt or waist chain: Wear a belt or waist chain and put it above the navel to cover the navel. Choose a style that matches your dance costume and use it as an ornament on the stage.
Choose a method that suits your dance and personal style, and make sure it doesn't affect your dance movements or comfort. In addition, before any form of physical modification or covering, we must respect our own comfort and boundaries.
