Japanese tend to wear very wierd and out there clothes that are border line Halloween costumes, whereas the Chinese look is more subtle and main stream. Chinese like to wear stuff from Versace, Gucci, Armani.
The Japanese as a culture do not wear “Halloween Costumes” you are referring to the harijuku style which is not a reflection of their culture. And Versace, Gucci, Armani is not traditional Chinese fashion either, nor are they “subtle” because obviously you’ve never seen a Chinese Opera. Modern fashion throughout both countries are very similar…they still have designer handbags, suits, dresses, blouses, shirts…so the above mentioned generalization is laughable and rather offensive
The Japanese sometimes wear kimonos – a traditional Japanese garment worn by women, men and children. Kimonos are traditionally T-shaped robes with hems that fall to the ankles, attached collars and long, wide sleeves. But today kimonos are most often worn by women, and on special occasions. They have also become more popular amongst Western fashion. And possibly, the Chinese dress more mainstream. However, it depends on their culture/where they live.
