I need your help! jpop clothes?

[AyuMayu]

I don't know if this is the right place to ask but...

I know it's a very strange request and I might not be able to find any answers but does anyone know where I can find the belt (or something similar) worn by the dancers in Namie Amuro's Can't Eat Can't Sleep I'm Sick video? I'm talking about the white one btw.

I've been looking for something similar for a long time so if anyone can help that would be great.
