group psychology of Japanese high school girls @ JR Yamanote Line Tokyo

I mean no offense, but to speak of extreme, according to my experience with bad memory, once in ten times I see girls wearing the same clothes if they get together more than three of them.

Especially Japanese high school girls like to do that I reckon.

I presume that being together more than three activates group psychology of Japanese high school girls.

Here I encountered the typical one.
Probably they had been to the Tokyo Disney Land.
