Odori obi , is a name for obis used in dance acts. An odori obi is often big, simple-patterned and has patterns done in metallic colours so that it can be seen easily from the audience. An odori obi can be 10centimetres (3.9in) to 30centimetres (12in) wide and 350centimetres (11ft) to 450centimetres (15ft) long. As the term "odori obi" is not established, it can refer to any obi meant for dance acts. Sakiori obi is a woven obi made by using yard or narrow strips from old clothes as weave. Sakiori obis are used with kimono worn at home. A sakiori obi is similar to a hanhaba obi in size and extremely informal.
