I wonder what was the thinking process of that Japanese person who decided : hmmm, what if I take very loose socks and glue them to my legs. Well, that doesn’t matter. Be you a tiny Japanese schoolgirl or an overweight computer geek you can purchase DX Rabbit brand (I wonder if I even want to know what DX stands for) sock glue and matching socks online.
Apparently Irish dancers also use sock glue. Also they probably use the glue on the theater seats for Riverdance performances.
In the Soviet Union a few of my classmates wore socks that could stay up like that without any glue. They also stuck to the ceiling if thrown up there.
