As mentioned in the above, the Edo bakufu regulated the way kimono were worn in minute detail in the O-oku, and the regulations passed on to daimyo families (feudal lord families), and finally the dress codes of the whole samurai class became pursuant to the codes and conventions of the O-oku (in and after the middle of the Edo period).
先述のように江戸幕府は大奥での着物を事細かに規定し、それが大名家にも普及し、武士階級全体で大奥慣習に準じるようになっていった（江戸中期以降）。
