Free size. I am 160cm tall. This is a set of yukata and obi that I purchased many years ago. The dark blue yukata has only been worn once. The lighter one has been worn for several seasons, but I had it dry cleaned each time. It has been dry cleaned this time as well. I would be happy if I could pass these on to someone who will cherish them. The obi has cherry blossoms on it, and it's reversible, with pink and light blue. The yukata colors are calm, so I think they can be worn by people of all ages.
