Tasuki (sash)

A tasuki (襷/たすき) is a fashion accessory used for holding up the long sleeves of the Japanese kimono. It is a sash made from either cloth or cord that loops over each shoulder and crosses over the wearer's back. The bottom of the kimono sleeves can then be tucked into the loop, holding them back for convenience and functionality.
