Seijinshiki is on the second Monday of January, and celebrated by those daughters and sons who turn 20 years old. The 20-year-olds gather for a special ceremony to celebrate reaching adulthood. The guys also dress in their best hakama, but today many of them wear suits. http://en.wikipedia.org/wiki/Furisode
Here is a pic of a group of ladies celebrating their Coming of Age Day. I am imaging their smiles reflect a happy day for them and a proud day for their parents.
I thought this young lady was a perfect model of a furisode. She is celebrating her Coming of Age Day.
The pictures reflect beauty, structure, tradition of the furisode kimono. Yes, the furisode is a beautiful garment, but I think they young ladies make them even more beautiful!
Website of Interests
I ran across this website (http://www.bookmice.net/darkchilde/japan/jkimono.html). This site discusses kimonos historically and the types of kimonos. There is a topic on furisode which include vintage furisode pictures.
