Hey, at least it's white. I had a friend who had a black binder. Yeah, that didn't work out well.
If you can't find a thick enough tank top/vest/whatever, you could probably alter a thicker t shirt easily enough.
Largely unrelated, what anime/manga/game/whatever is he from? I've seen a few pictures of that character around the Internet and I have no idea who he is.
