Our polyester Obi belt with Color Options are traditionally worn over the Yukata or Kimono for public occasions and festivals to give a formal appearance. This obi is less formal and easy to tie. The Obi Belt is simply wrapped around the waist once or twice and a pretty bow is tied in the back. Also a good size for younger children and teens. The small matching sash belt that comes with a kimono or yukata is usually worn at home, bath houses or as night attire.
