Hanhaba obi (半幅帯[17] / 半巾帯, "half-width obi") is an unlined[16] and informal obi that is used with a yukata or an everyday kimono.[15] Hanhaba obi are very popular these days.[18] For use with yukata, reversible hanhaba obi are popular: they can be folded and twisted in several ways to create colour effects.[19] A hanhaba obi is 15 centimetres (5.9 in) wide and 300 centimetres (9.8 ft) to 400 centimetres (13 ft) long. Tying it is relatively easy,[18] and its use does not require pads or strings.[14] The knots used for hanhaba obi are often simplified versions of bunko-musubi. As it is more "acceptable" to play with an informal obi, the hanhaba obi is sometimes worn in self-invented styles, often with decorative ribbons and such.[18][19] - Wikipedia, 13/5/2020
