Young Brunette Girl With A Red Belt Strap Outside On The Field

• Skateboarders often wear shoelaces in belt loops to hold pants up instead of a conventional belt. This is done for fashion and because of the buckle on a belt often digs into a skater's stomach when skating, where as to the shoelace has no buckle. The other reason this is done is if the skater falls they don't land on the belt causing more pain.
It is also used in judo, karate and other martial arts, where different colors may indicate rank or skill.
• A breast belt is a belt worn by women that holds their breasts up, making them appear larger or more prominent underneath clothing. It is worn generally above or on the stomach but just beneath the breasts.
