Now we can see boys and girls in formal dress such as kimono taken by parents to a shrine around November 15th.
Kamioki(髪置) was a event that 3-year-old girls (and boys in many areas) grew their hair out from this day.
The girls tie flat sash attached to kimono instead of obi.
Now 3-year-old girls wear hifu(被布) on kimono at Shichi Go San. Originally, hifu was a kind of jackets that is put on over kimono for men.
Obitoki(帯解) was a custom done by the families of commoners for 7-year-old girls. From this day, they started to put on obi(sash) in place of cloth bands.
In addition, hakoseko(筥迫) is tucked between collars. Hakoseko is a take-along box-shaped purse for women.
