The term zari (Persian for 'gold') is a general term used to describe these braids, often gold coloured, which are sometimes combined with beads. Occasionally this type of braid may also be called shak, using another Persian term for this form of work. Sim is another form of braid, but much simpler in appearance than zari, and made from a combination of coloured cotton and metallic threads. Both the zari and sim braids are used to embellish garments, especially around the neck openings, sleeve cuffs and ankle cuffs. Similar, locally made braids are still made and worn by women in the Bandar region of southern Iran.
