I've seen quite a few kids in my area wearing these baseball caps, which have "South" or "North" in the Tube Roundel, so it's obviously a bit of a "Street" thing, rather than a desire for all things Tube!
Not loving the blingy chain around his neck, but at the same time he's also wearing some charity wristbands and engrossed in completing a Sudoku puzzle, so he's quite a puzzling contradiction himself.
So with me the jury's out. I'm still not sure whether he can be classed as totally a fashion victim or just a pretty streetwise kid! Any other thoughts?
