I 16 years old, X-legged, girl, not too thin, wearing nothing looks good. One treatment is to use a corrective belt, but some people say it hurts muscles and bones. what can I do?

This situation is normal, you can't do surgery, which will do you great harm. Besides, I think it's just your psychological factors. You may be too harsh on beauty. And if you want to change it, I suggest you pay attention when you walk. The inner figure of eight (toes are retracted when you walk) is easy to form an X-shape. Keep your toes straight forward or slightly outward when you walk, and gradually develop good habits and correct them ~ ~
