How do you keep your cummerbund from raising up?

To keep your cummerbund from raising up, ensure it fits snugly around your waist and is properly adjusted. It should sit at your natural waistline, above your pants, and be secured with the appropriate fasteners. Wearing a dress shirt that is tucked in securely can also help keep it in place. Additionally, consider using shirt stays or garters to maintain a polished look.
