People wearing Yukata (Traditional summer dress) is a common sight in Japanese summer festivals. Made of cotton, yukata is cooling and comfortable to wear in summer.
Yukata is different from kimonos; kimonos are made of silk, thicker due to inner lining, and are more detailed. However, both Yukata and Kimono are accmpnanied by wooden sandals and traditional-styled handbags.
Children and youth wear bright colors, while older people usually wear dark blue and white patterns. Occasionally, we can see characters like Hello Kitty or Mickey Mouse, on young women's or children's yukata.

Japanese youth hostels and most of the hotels provide a Yukata for use after bathing. However, these are light colored and have a thin belt.
Being much cheaper and comfortable than a kimono, Yukata is a popular souvenir among foriegn tourists.
