These days in 日本橋 Nihombashi, you can see a lot of young couples or the usual 3 girl friends groups, strolling around in a "My Yukata summer plan afternoon shopping and gazing at the Nihombashi Grands Magasins" in the historic glamorous old town of central Tokyo.
Young women (suddenly acting traditional Japanese, with a little bit of timidity and appreciation of the cultural heritage) are seen walking close but not too close to their boyfriends wearing Yukata, it is in fashion. http://www.nihonbashi-tokyo.jp/enjoy/feature/201308/
This scorching summer sun is an opportunity to appreciate how refreshing it is actually to wear a Yukata ( I tried) http://www.nihonbashi-tokyo.jp/en/index.html
Thing is young people do not necessarily know how to fix it. Especially how to firmly fix the Obi. How to wear a Yukata with style? http://the-japan-news.com/news/article/0001499690
