The most common terms for this type of red ribbon are "sash" or "decorative ribbon."
Terms for Traditional Contexts
In wedding attire or costumes for celebratory performances, they are typically referred to as "silk ribbons" or "tasseled ribbons." They are often found on the lapels, cuffs, or waists of garments like *Hanfu* or *Qipao*-for instance, the ribbons draping from the shoulders of a bridal gown.
Terms for Modern Clothing
Red fabric accents on casual wear, school uniforms, or sportswear are generally called "decorative ribbons" or simply "ribbons"-such as the adjustable ribbons found on the cuffs of baseball jackets.
Terms for Functional Markers
If the ribbon features text or emblems, it is classified as a "marker ribbon" or "honor sash." These are commonly seen as military sashes or ceremonial badges worn at award events-such as the red satin sash worn diagonally across the chest at a school awards ceremony.
Tips for Distinguishing Contexts
You can further differentiate them based on material (satin vs. cotton/linen), placement (collar vs. waist), and attachment method (sewn-on vs. detachable). For example, the ribbon at the back waist of a formal gown is usually made of satin and sewn in place, whereas the red ribbon attached to an employee ID badge is typically a detachable woven strap.
