Belt settings are a type of clothing accessory that can be used to adjust the fit of a garment around the waist. The term 'belt settings' is derived from the 6-letter word 'waists, ' which refers to the part of the body where the belt is typically worn. Belt settings are commonly used to adjust the size of a garment, such as a dress or skirt, and can also be used to add a decorative element to an outfit.
