Prolly a typical Japanese padded bra, I imagine. Although with the whole freakish "8 year old face/16 year old body" Meimei thing, nothing would surprise me at this point.
i have not noticed Meimei's body, but damnit that means i will next time. thanks. ._. what struck me the most about Karin there is that she's looking a lot taller. i remember i used to point her out during concerts as the tiny little thing dancing around pretending to be a big girl.
