The term 'waist accessory' can be summarized as a SASH, which is a four-letter word. A SASH is a long strip of fabric that is worn around the waist, often as part of a traditional costume or uniform. It is usually made of silk, satin, or velvet and is decorated with embroidery, tassels, or other embellishments. Sashes are also used to denote rank or status in some organizations, such as the military or police.
