I sometimes wear my AT08 hoodie, and I wore it after the concert that night.
Erm, I have the AT09 and AT10 t-shirts, but have never really worn them. I only got them because I was at the merchandise stand and wanted some stuff to buy
They don't seem to fit right on me, and I don't think I'd be brave enough to walk around the city in them either... haha
I wore the AT10 sweatband during the concert this year, but haven't needed to use it since
However, I do wear my Kumi Koda t-shirt quite a lot
