The so-called anti-fashion, as the name implies, is that his works are very complicated and cumbersome. There is no way to reflect the beauty of women. This fashion can be said to be unacceptable to many people, because now is an open-minded era after all, and many people want to put their beauty outside, but yohji yamamoto's works tightly wrap the beauty of women in kimonos.
Moreover, his works are particularly monotonous in color, mainly red and black. In fact, this is also to express some traditional oriental aesthetics in his mind. We all know that the aesthetics of orientals are always conservative, so red and black are more in line with the aesthetics of orientals, which may be the reason why these two colors are favored by yohji yamamoto!
To sum up, with red and black as the main design colors, yohji yamamoto mainly wants to express his oriental aesthetics. Oriental aesthetics runs counter to western aesthetics. He won't use many particularly bright colors to attract people's attention, but will use some large areas of dark colors, which will be more conservative and natural. These two colors are also more in line with his design concept.
