The samurai women wore the "uchikake" dress for winter in the normal style.

And as a full dress of summer, they removed the upper half of the "uchikake" dress, and they twisted it around the waist in summer.

This is called the "koshimaki-sugata (=twist-around-waist style).

As a full dress of summer, this style was descended to the Edo period.

However, since the"aida-gi" was visible from outside, dyeing was applied to the "aida-gi" of summer in the Edo era .

Moreover, the patterns of "uchikake" dress were simplified.
