I attached buttons to the shirt, so I have done the shirt making! The name “Kawamichi” is about over 100 years old and used to be a family of fishermen. The current Kawamichi Shoten store is a renovated hut that was used as a fisherman’s workspace about 50 years ago. It used to be a shop that sells daily necessities. When I was a child, I liked to look into the boxes of needles, threads, and buttons. Suddenly, I remembered the box that contained the button, and when I looked for it. I found the box still in the shop! And I opened it, and there are shell buttons in it! So I attached The shell buttons on the shirt.
